Thanks.  Please state in the comments to each mode with which grammars
is it compatible, so that users could know from which URL to download
the required grammar libraries.  The heex-ts-mode mentions that, but
elixir-ts-mode doesn't, AFAICT.

I think these modes should go to the master branch, so "30.1" is more
accurate.

Copy/paste error, I presume?

Thanks.
