Ruby LSP adoption

[vinistock]

One of the main goals of Rubydex is to have it be the code intelligence engine for the Ruby LSP. To make adoption gradual and allow us to find bugs, we're going to cut beta releases of the LSP as we adopt Rubydex.

The steps to fully adopt Rubydex are:

Foundation

• Add Rubydex as a dependency Add rubydex dependency ruby-lsp#3991
• Start performing initial indexing and resolution on boot Start indexing and resolving Rubydex graph ruby-lsp#3992
• Update the Ruby LSP's singleton class name representation to match Rubydex's Switch singleton class names to new style ruby-lsp#3993
• Migrate Ruby LSP's type inferrer to use Rubydex graph Migrate type inferrer to use Rubydex ruby-lsp#4014
• Start consuming incremental changes upon edit and on file watched notifications Update graph on edits ruby-lsp#4032

Features

• Go to definition Partially migrate go to definition to use Rubydex ruby-lsp#4015 Handle visibility in go to definition ruby-lsp#4095
• Hover Partially migrate hover to use Rubydex ruby-lsp#4029 Handle visibility in hover ruby-lsp#4097
• Signature help Migrate signature help to Rubydex ruby-lsp#4098
• Completion Partially migrate completion to Rubydex ruby-lsp#4096
• Workspace symbol Migrate workspace symbol to use Rubydex ruby-lsp#4019
• Rename Migrate rename to use Rubydex ruby-lsp#4033
• Find references Migrate find references to Rubydex ruby-lsp#4066
• Type hierarchy Migrate type hierarchy to use Rubydex ruby-lsp#4072
• Test discovery (we use ancestors to detect test framework) Migrate test discovery to use Rubydex ruby-lsp#4064

Add-ons

• Migrate Rails add-on to Rubydex
  • Update Ruby LSP dependency to allow beta version and update gems ruby-lsp-rails#705
  • Migrate go to definition to Rubydex ruby-lsp-rails#706
  • Migrate hover to Rubydex ruby-lsp-rails#707
  • Migrate rails test style discovery to Rubydex ruby-lsp-rails#710
  • Remove indexing enhancement ruby-lsp-rails#711
• Migrate Tapioca add-on to Rubydex Migrate Ruby LSP add-on to Rubydex tapioca#2620

Documentation

• Remove type hierarchy from experimental (it should be a stable feature now)
• Review if any add-on related APIs need to be documented again

Clean up

• Remove all code related to the old indexer Remove old indexer ruby-lsp#4101
