Follow-up to #17934

This PR addresses a few additional VS Code configuration things.

First, the Ruby LSP configuration now runs brew install-bundler-gems --add-groups=style,typecheck,vscode before starting the LSP. This should automatically install everything and keep the LSP up to date for new users.

Additionally, editor.formatOnType is now turned on for ruby files. This handles a few things, but a big one is that it will automatically add end statements and handle indents. This removes the need for the kaiwood.endwise VS Code plugin, so I have removed it.

Finally, this PR adds the --lsp option to brew typecheck which allows us to actually enable the Sorbet plugin and view live type info (much of the code here comes from @Bo98).
