Add Dune (OCaml build system) (#6814)

* Add Dune

* Remove dune-file which only has one use

* Merge all Dune entries into the same languages

Since they all share the same grammar, they should just be considered as
one language. The grammar used also only defines one source.dune scope.

* Reduce scope to just dune-project

- `dune` is only used by a bit over 100 repositories (5 pages), the
  1.8k in the search results isn't what we're counting here
- The two workspace files have even fewer uses
