Install broken for melpa-stable?

Pygn-mode CI:

• https://github.com/dwcoates/pygn-mode/pull/197/checks?check_run_id=3630901761

Is failing like this:

I don't know Cask very well, but apparently it is installing tree-sitter-langs v0.10.6-alpha because that's the latest tag (and there's no way to pin Cask to an earlier version). Then it's attempting to install v0.10.6-alpha artifacts which don't exist. The Caskfile is using melpa-stable as the source.

Is there a way to override the version attempted for the grammar bundle install? If not, would you accept a PR to add an override via getenv?

I entirely forgot about melpa-stable... The above tag will have binaries as soon as I fix the release pipeline. I'll also change the MELPA recipe to restrict it to a subset of tags.

The Caskfile is using melpa-stable as the source.

I think melpa-stable is discouraged in general. There's even a proposal to abolish it. Maybe it's better to change the Caskfile to use melpa? (In my own experience, melpa-stable got broken more frequently than melpa when I was still using it.)

There's no way to override that at the moment. I think changing tree-sitter-langs--bundle-version to a defvar is cleaner than getenv. However, it wouldn't help in this case, since cask doesn't have pre-install hooks.

The release pipeline is working now, so the pygn CI pipeline should work if you re-run it.

Thank you!
