Add Semantic Token Support
Description
Hi, it would be great if this language server would be able to add semantic token support so integrations with IDEs are easier to work with, namely syntax highlighting.
For example, instead of building a syntax highlighter from scratch, many plugins and libraries out there are equipped work with a LSP to have this feature out the gate.
There are a lot of examples of LSPs that have implemented this, some of which are highlighted on this reddit post: https://www.reddit.com/r/neovim/comments/1bxx7pc/which_language_servers_support_semantic_token/?rdt=62164
The specification for Semantic Tokens is available here: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_semanticTokens
