tls: use Go default kex for the moment that include PQC (#6542)
By default Go 1.23 enables X25519Kyber768, a post-quantum key agreement
method that is enabled by default on Chrome. Go 1.23 does not expose
the CurveID, so we cannot add it by specifying it in CurvePreferences.
The reason is that X25519Kyber768 is a preliminary key agreement that
will be supplanted by X25519MLKEM768. For the moment there is value
in enabling it.

A consequence of this is that by default Caddy will enable support
for P-384 and P-521.

This PR also removes the special code to add support for X25519Kyber768
via the Cloudflare Go branch.

// Package main is the entry point of the Caddy application.
// Most of Caddy's functionality is provided through modules,
// which can be plugged in by adding their import below.
//
// There is no need to modify the Caddy source code to customize your
// builds. You can easily build a custom Caddy with these simple steps:
//
// 1. Copy this file (main.go) into a new folder
// 2. Edit the imports below to include the modules you want plugged in
// 3. Run `go mod init caddy`
// 4. Run `go install` or `go build` - you now have a custom binary!
//
// Or you can use xcaddy which does it all for you as a command:
