feat: integrate with lspconfig's on_setup hook (#631)

* feat: integrate with lspconfig's on_setup hook

* fix!: don't use aliased installation directories if new .setup() fn is used

This makes it so servers are always installed in a directory name that
corresponds with the server name. The reason aliased installation directories
is supported is lost on me, but it's legacy and complicates things
unnecessarily.

This is a breaking change for users who previously were using the `.on_server_ready()`
hook, and now transitioned to setting up servers directly via lspconfig.
These users will need to reinstall the server.

* fix: block usage of the deprecated server:setup() method if new setup method is used

* fix: allow passing no arg to setup()

* docs: ok final.v3 readme
