Highlight common keywords

[mrsdizzie]

For Github / Gitlab / Gitea etc... they all support common keywords for referencing issues in a commit message:

https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword

It would be nice to highlight those as well.

I'm not sure what underlying tree sitter parser is used since it isn't shown or committed in this repo

You're right, I really should add the Tree-sitter grammar to this repo. I wanted to add it as a submodule, but the Makefile provided by Panic needs to be in the same directory as the grammar. I haven't had time to tweak that so that I can keep the Makefile in my repo alongside the grammar submodule, and then make the extension reproducible.

But anyway, the Tree-sitter binding is from gbprod/tree-sitter-gitcommit. It would be there that support for these keywords would need to be added.

OK, there wasn't actually much to adding the Tree-sitter binding to the repo and getting the Makefile to work with it (see e7a01e4 and 1bf3961). It should now be possible for you to run this extension locally, installing it in Nova from source rather than from Panic's Extensions store.

If gbprod/tree-sitter-gitcommit does add the keywords you're looking for, please do create a PR here with the updated submodule.
