fix(angular): re-fix angular html treesitter (#3488)

This was previously attemped to be fixed by
https://github.com/LazyVim/LazyVim/pull/3469, which caused an issue with
angular LSP.
The PR was reverted as mentioned in
https://github.com/LazyVim/LazyVim/pull/3485.

This PR implements suggestion by @folke, which fixes treesitter without
breaking LSP.
