FR: Make available as LSP

[chrisgrieser]

Many formatters/linters such as biome or ruff are also available as LSP, even though they aren't "real" language servers.

Offering an LSP, even if it is just for the formatting command, has its advantages, as it allows for easier integration into editors. With editors like nvim, for example, integrating stylua requires an extra plugin, while an LSP could be used out of the box.

Interesting idea. I can see the value in this, although building out a fully fledged language server that conforms to the protocol might be a bit overkill for the tool itself. Maybe it should be a wrapper binary tool, not sure yet.
