Extend groovy support (#9677)

* Extend groovy support

Use more complete parser introduced in nvm-treesitter in
https://github.com/nvim-treesitter/nvim-treesitter/commit/d4dac523d2546afc266eb9b5a7986690b5319c41

* Update runtime/queries/groovy/locals.scm

Co-authored-by: Michael Davis <mcarsondavis@gmail.com>

* Drop indent.scm for groovy

It was copied from the tree-sitter repository but is not
compatiblw with the way indent queries are implemented
in Helix.

* Adapt groovy highlights to helix syntax

* Update documentation
