feat(treesitter): follow upstream captures (#694)

* feat(treesitter): follow upstream captures

This PR primarily updated highlight groups related to treesitter captures to
comply with the updated specification. Deprecated captures were relocated to the
legacy section. All changes are based on the following four commits:
- nvim-treesitter/nvim-treesitter@99ddf57
- nvim-treesitter/nvim-treesitter@5d75359
- nvim-treesitter/nvim-treesitter@dccf31f
- nvim-treesitter/nvim-treesitter@998b230

I've attempted to keep the colors consistent for new additions by looking at the
definitions of existing captures, but I'm _really_ not sure how to handle colors
for documentation-related ones. AFAIU the only relevant existing capture is
`@markup.raw`, but it seems better suited for smaller sections of documentation.
Personally, I don't think a large block of greenish-blue would look great for
extensive documents that might span multiple lines.
