feat: add tree-sitter-based token provider for GritQL

[daivinhtran]

VSCode provides several ways to support highlighting

1. TextMate grammars (similar to feat: add syntax highlighting for GritQL biome-intellij#195)
2. Semantic Token Provider
   a. Using Regex to determine tokens
   b. Tree-sitter integration: Use tree-sitter-gritql and map syntax nodes to semantic tokens

This PR aims for 2.b. and implements a mapper from tree-sitter-gritql's syntax nodes [1] to VSCode's sematic tokens [2]. This is the cleanest way since we get to avoid the whole legwork of comprehending the GritQL grammar from the ground up.

Fixes: #686

Good start! I left some comments to address

This Todo should also explain how to address itself. Like, there's a reason why you couldn't implement it in this PR

Thanks! I added more context in the TODO comment.

Essentially, honeycombio/tree-sitter-gritql#28 is the blocker.

Thanks @ematipico for reviewing. I cleaned up my the PR. PTAL!

I got my prototype for tree-sitter integration working in daivinhtran#1. honeycombio/tree-sitter-gritql#28 is the blocker before we can move forward with tree-sitter.

Anyways, this PR is a stepping stone and will make the work easier down the road.

@ematipico I reworked the PR to integrate with tree-sitter since honeycombio/tree-sitter-gritql#28 is now resolved.
