docs: update boilerplate links (#1515)

Updates to some of the boilerplate links in the docs:

- "Join our online chat" now goes to Charm Development instead of Ops
Library Development
- "Report bugs" now goes to GitHub issues instead of the repo home
- Adjusted "doc" to "docs" in the title of the issue that's started if
you click "Open a GitHub issue for this page"
