[Feature/giscus] add giscus support

[sgamerw]

Description

add giscus support, not add config to site.config.ts, maybe too simple and crude, but it works.

Notion Test Page ID

I test it locally, and comment success to giscus repo.

Thank you for this PR, but please don't use these as the default, otherwise people who haven't configured the values with their own repo will spam the giscus repo with their discussions.

[sgamerw]

so, maybe just keep these configuration empty, then tell users how to set these in docs/wiki/readme?

[sgamerw]

I haven't add configs to site.config.ts, there are too many values, so what's your suggestion?

[sgamerw]

@laymonage already remove the giscus repo information, made these keys into config for giscus.

[transitive-bullshit]

This looks like a really great starting point for Giscus support, which I'm a fan of. I don't think it should be enabled by default or, as you mentioned, it should be optional and configured via the config file.

[sgamerw]

Thanks for reply, I'll add config for Giscus ASAP.
