## Description
Solargraph already delegates some diagnostics to Rubocop by itself if it
is installed on your system. However, if Rubocop is also enabled as an
LSP while you're using Solargraph, then all Rubocop diagnostics are
going to be duplicated and shown twice. Once from Solargraph after it
calls Rubocop, and again by Rubocop separately running as an LSP.

## What is this PR for?
Shopify started working on its own LSP
(https://github.com/Shopify/ruby-lsp) and it performs way better than
Solargraph which has a lot of limitations. This paired with sorbet gives
better IntelliSense when navigating the code.
This PR follows the same approach as Python and lets the user configure
through vim.g options the lsp and formatter for ruby, without overriding
any configuration.
## Does this PR fix an existing issue?
One caveat though is that RubyLsp does not work very well with NeoVim <
0.10 https://github.com/Shopify/ruby-lsp/blob/main/EDITORS.md#neovim
