Chore: Handover to AWS Plugins

[iwysiu]

Add basic templates and processes:

• - CODEOWNERS
• - Bugs
• - FR (to Discussions)
• - PR template
• - Automate CHANGELOG
• - Levitate (as comments)
• - Add to project board (for the new squad)

This does not include: Code coverage

• Before closing this issue, we should test them out.

I am not aware of any of our other repos which have automated changelogs besides main Grafana.
It seems possible, but require labels and milestones and eventually implementing the labels/milestones requirements for merging. I think that could be an interesting feature to add, but maybe a little too much for this handover task.

Also I think none of our other repos have PR templates. I've added one in the TwinMaker PR which I think could be nice to add to our other repos.
