[docs] Enable some new features (#2623)

Browse source 
* [docs] Enable a bunch of markdown extensions

* details makes admonitions collapsible and when started with ???
  instead of !!! they'll be collpased by default
* highlights are updated to include linenums by default but with a style
  that doesn't result in the linenums to be copy-pasted when selecting
  and pasting. This makes it possible to directly link to a specific
  line in the documentation instead of just the general page
* caret, mark and tilde make it possible to highlight text and have
  super/subscripts
* keys turns combos like `++ctrl+alt+del++` into HTML key elements
  showing a keyboard combination to press
* tabbed makes it possible to have tabs within a document. Right now we
  have different sections sometimes to show the config for nginx, apache
  and Caddy, which can be turned into tabs instead and which tab is
  picked will get remebered
* smartsymbols turns certain things, like `(c)` in the right symbol ©

* [docs] Upgrade all the python dependencies

* [docs] Explain how to update conda deps

If you don't use Conda, you can read the `docs/environment.yml` to see which dependencies are required and `pip install` them manually. It's advisable to do this in a virtual environment, which you can create with something like `python3 -m venv /path-to/store-the-venv`. You can then call `/path-to/store-the-venv/bin/pip`, `/path-to/store-the-venv/bin/mkdocs` etc. If you don't use Conda, you can read the `docs/environment.yml` to see which dependencies are required and `pip install` them manually.

In order to upgrade dependencies, use `conda update --update-all` in the activated environment. You can then update the `environment.yml` with `conda env export --from-history -f ./docs/environment.yml`, though you'll need to fix the `channels`. Beware that `conda env export` will also drop the `pip` dependencies, so make sure to add those back.

For nginx, you'll need to start by configuring a cache zone. The cache zone must be created in the `http` section, not within `server` or `location`. For nginx, you'll need to start by configuring a cache zone. The cache zone must be created in the `http` section, not within `server` or `location`.

} }
``` ```
This configures a cache of 10MB whose entries will be kept up to one week if they're not accessed. This configures a cache of 10MB whose entries will be kept up to one week if they're not accessed.
The zone is named `gotosocial_ap_public_responses` but you can name it whatever you want. 10MB is a lot of cache keys; you can probably use a smaller value on small instances.

The `proxy_pass` and `proxy_set_header` are mostly the same, but the `proxy_cache*` entries warrant some explanation: The `proxy_pass` and `proxy_set_header` are mostly the same, but the `proxy_cache*` entries warrant some explanation:

- `proxy_cache_valid 200 10m;` means we only cache 200 responses from GTS and for 10 minutes. You can add additional lines of these, like `proxy_cache_valid 404 1m;` to cache 404 responses for 1 minute - `proxy_cache_valid 200 10m;` means we only cache 200 responses from GTS and for 10 minutes.

- `proxy_cache_lock on` means that if a resource is not cached and there's multiple concurrent requests for them, the queries will be queued up so that only one request goes through and the rest is then answered from cache - `proxy_cache_lock on` means that if a resource is not cached and there's multiple concurrent requests for them, the queries will be queued up so that only one request goes through and the rest is then answered from cache
- `add_header X-Cache-Status $upstream_cache_status` will add an `X-Cache-Status` header to the response so you can check if things are getting cached. You can remove this. - `add_header X-Cache-Status $upstream_cache_status` will add an `X-Cache-Status` header to the response so you can check if things are getting cached. You can remove this.
The provided configuration will serve a stale response in case there's an error proxying to GoToSocial, if our connection to GoToSocial times out, if GoToSocial returns a `5xx` status code or if GoToSocial returns 429 (Too Many Requests). The `updating` value says that we're allowed to serve a stale entry if nginx is currently in the process of refreshing its cache. Because we configured `inactive=1w` in the `proxy_cache_path` directive, nginx may serve a response up to one week old if the conditions in `proxy_cache_use_stale` are met.

The `/fileserver` location is a bit special. When we fail to fetch the media from disk, we want to proxy the request on to GoToSocial so it can try and fetch it. The `try_files` directive can't take a `proxy_pass` itself so instead we created the named `@fileserver` location that we pass in last to `try_files`. The `/fileserver` location is a bit special.

Nginx does not add cache headers to 4xx or 5xx response codes so a failure to fetch an asset won't get cached by clients. The `autoindex off` directive tells nginx to not serve a directory listing. This should be the default but it doesn't hurt to be explicit.
