Add kotlin language (#1689)
* Add kotlin language

Queries taken from https://github.com/nvim-treesitter/nvim-treesitter/blob/master/queries/kotlin seem to work well enough for my needs though I don't use kotlin heavily.

* Update lang-support doc

* Updates the kotlin highlight query to use helixs scopes

* Updates the queries from PR feedback

* Adds 'shallow = true' to gitmodules

* Removes kotlin locals.scm

* Remove blank line
