Add new tree-sitter groups from neovim

[stnley]

nvim-treesitter and subsequently neovim is aligning their capture/highlight groups with upstream tree-sitter. This adds groups as of nvim 0.10 (unreleased). Existing groups are untouched.

I tried to align to what they were before, however there are some slight differences due to tree-sitter queries.

This screenshot shows previously working groups on left, this PR on right:

Note, this depends on #318 landing.
