neovimUtils.grammarToPlugin: also move the queries (#321550)

This installs queries from source into the neovim expected folder.

Some grammar queries are already in a folder like expected by neovim but others (notably the treesitter official ones) are not so the code deals with both. 
For instance the koka grammar puts its queries directly in "queries" folder https://github.com/mtoohey31/tree-sitter-koka/tree/main/queries
but some others puts it in a folder expected by neovim like https://github.com/tjdevries/tree-sitter-lua/tree/master/queries/lua .
