Add giscus support (#3022)

* Add script in same style as utterances

But adjusted for the various filed differences

* Add initial script

* Add default settings

* Update changelog

* Add feature to readme

* Add comments html

* add comment provider include

* update config in docs

* Add URL for additional reference

* docs for giscus comments

* Unrelated bugfix: add missing version separator

So that things match the "history" doc.

* add space

* update history doc

* update about doc

* add to test config yaml

* remove unnecessary / incorrect async attribute

* probably should pass the right config paths

* lowercase the repo name

* Update docs to address '1' and '0' for reactions_enabled

Figured I'd match the giscus format rather than convert a boolean to an int there.

* update two additional docs

* docs wording fix

+#### giscus comments
+
+To use giscus you will need to [install the app](https://github.com/apps/giscus) to your GitHub repository.
+
+The next step is to go to <https://giscus.app> and fill out the desired settings. This will generate JavaScript that will provide you with the settings you will need to configure things below.
+
+You'll need to ensure you've added the following to `_config.yml`:
+
+```yaml
+repository: # GitHub username/repo-name e.g. "mmistakes/minimal-mistakes"
+```
+
+**Note:** Make sure the repo is public, otherwise your readers will not be able to view the issues/comments. The [discussions feature](https://docs.github.com/en/discussions) also needs to be active on your repo.
+{: .notice--warning}
+
+To enable giscus on the front end set `comments.provider` and the other additional options.
+
+```yaml
+comments:
+  provider: "giscus"
+  giscus:
+    repo_id              : # Shown during giscus setup at https://giscus.app
+    category_name        : # Full text name of the category
+    category_id          : # Shown during giscus setup at https://giscus.app
+    discussion_term      : # "pathname" (default), "url", "title", "og:title"
+    reactions_enabled    : # '1' for enabled (default), '0' for disabled
+    theme                : # "light" (default), "dark", "dark_dimmed", "transparent_dark", "preferred_color_scheme"
+```

 #### Static-based comments via Staticman
 
 Transform user comments into `_data` files that live inside of your GitHub repository by enabling Staticman.
