Proposed changes

Adding support for https://giscus.app/ commenting. Comments and Reactions are added and tracked in GitHub discussions. This commenting system works similarly to Utterances.

Giscus is loaded in the comments.html partial by referring to the giscus.html partial. Since single.html layout loads comments if comments are enabled, you must ensure both the comments and giscus parameters are configured in Site Params.

Screenshots, if applicable

Thanks for this one too. I have not tested Giscus before, have you tested these changes yourself?

Please also sign off on your commits (DCO) so we can accept this.

Hey @chipzoller - It looks like my commit was signed off:

Looking at the DCO check, it's actually your update to the readme that isn't signed off?

✅ I have tested this personally in my own website. I switched from Utterances to Giscus awhile back and wanted to contribute the code back for others to use (and so I can stop using partial overrides). 😄
