Remove solargraph

This is a Ruby LSP that I no longer use, because I'm on RubyMine full-time.

My immediate motivation for this change is that solargraph's eventual dependency on the `parser` gem triggers warnings on all Rails commands, hinting that it doesn't support the *exact* Ruby version we use.

This could potentially be resolved by upgrading Solargraph or some of its dependencies, but since I'm not using it anyway, may as well just remove!
