Neovim: Update tree-sitter support for CSS

[tientrinh21]

Hello! I found that dracula/vim worked well with HTML & JS via tree-sitter but not CSS. So I took some time to add some highlights for it; I tried to make it look like Vscode as much as possible.

What I linked:

• Make ,, ., ;, etc. become pink: TSPunctDelimiter -> DraculaPink
• Make selectors become pink: TSType -> DraculaPink
• Make classes, properties become cyan: TSProperty -> DraculaCyan
• Make URLs become orange: TSError -> DraculaOrange (I was inspired by how shaunsingh/nord.nvim did it)

Neither Derek nor I is working on it, I believe. We requested some changes which have not been implemented.
