Make installable via LuaRocks

[FourierTransformer]

With this PR in place teal-language-server can now be installed on systems with LuaRocks 3.10.0+ and Node installed!

Changes

• Switched to ltreesitter-ts which bundles the tree-sitter library as well as ltreesitter.
  • I put in an issue in the ltreesitter repo about potentially including the library as part of the bindings
• Updated rockspec for the eventual new version
• Added running tests as part of GHA
• Updated LuaRocks to 3.10.0 in GHA (used to be 3.8.0)

Current Issues

• Need to see if we can drop Node as a requirement. If the tree-sitter CLI can generate a grammar from the JSON file without Node, it should be possible.
• It will only install on LuaRocks 3.10.0 and above
  • This is due to the changes that happened to custom build systems in 3.10.0. When I was working on tree-sitter-cli, I was initially targeting 3.8.0, but ran into issues with newer versions of LuaRocks. I'm sure there's some way to get it all working.

Not sure why the build is failing, planning to have it fixed before merging. The script works locally and my hererocks [local] setup also works just fine. When installing tree-sitter-cli, it seems to not be able to find the builder for it, which is a bit odd.

Turns out it worked locally because I had the tree-sitter-cli builder installed at the system level and it was finding that. When I removed it, I started getting the same error message.

The error message was about not being able to find the builder, which got fixed by upgrading to LuaRocks 3.10.0+. I think there might by ways to support versions below 3.10.0. I'll investigate that a bit, and see what can be done. The workaround for now is updating LuaRocks to 3.10.0+.

I'll continue tracking some of this in #26
