Environment information

macOS 12.5.1
VSCode v1.71.0
Rome extension v0.14.1

What happened?

While adopting Rome for an existing codebase, I regularly need to edit rome.json and work with the revisited changes. There is currently no way to restart the LSP from the command palette other than the very heavy-handed "Reload Window" command. This has several undesirable side effects, such as losing recent file edit (undo) history.

Expected result

It would be nice to have a "Restart LSP Server" command, similar to other LSP extensions.

Automatically updating the LSP config when rome.json changes (#3195) would go a significant way towards many of the use cases for a "Restart LSP Server" command.

But there are some cases where it's useful to restart the LSP server even when rome.json hasn't changed, such as when you are re-compiling the LSP binary in-place (e.g. because you're recompiling it from scratch during developement/debugging of Rome itself).
