giscus support

[patgarz]

I'm reaching the finishing stages of adding giscus comments support for my Beautiful Jekyll site. If you're not familiar, giscus is what I would consider the "spiritual successor" to utterances as it uses GitHub Discussions rather than GitHub Issues for its comments.

Do you have any interest in me putting together a PR to add that functionality? Setup is almost identical to utterances so I don't think it adds much, if any, complexity (apart from a slightly longer config file).

Thanks for reaching out! Would this only involve adding a fee more fields to the config file and no other changes?

[patgarz]

To any consumer, yes. For anyone wanting to dive into the site code, they'll also find the giscus-comment.html included in _includes and a reference in comments.html (nearly identical to utterances).

I'll go ahead and put together the PR and link it here so you can see the exact diff - should be able to do that after I'm off work this evening.

OK that sounds like a small enough change. Please do go ahead, and make sure to also update the CHANGELOG and README accordingly

Closign the issue, as it's already in a PR
