Overview

Add index.md page

Rationale

This page was the output of documentation practice work for standardising Charmhub documentation. Specifically, the repo-policy-compliance charm was pinpointed as a small charm existing within the larger context of another documentation set (the GitHub runners). Therefore, it's an ideal candidate for a single-page Charmhub doc that covers the bare minimum of the charm and points to the larger doc set.

The page follows a template produced by the Canonical technical authors. Thanks to Christopher for help with filling in the necessary technical details!

Nice!

Thank you Erin. I have a few comments. You are also right that since there is no code change, a version bump is not required, but I think it would still be good practice to bump it (so that basically every commit on the main maps is to a different version.) Could you bump it from 1.10.1 to 1.10.2?
