Subject: [PATCH] add-to-project workflow: automatically add reviewers without
 need of CODEOWNERS (#37)

## Description

automatically add reviewers without need of CODEOWNERS, reviewers are
added if and only if the PR is not in draft mode.

The recommendation is to start the PR in draft mode, and move it to
ready only when actually ready for review.

While CODEOWNERS is very powerful, it would require to add such file to
all repositories.

## Changes Made

* add specified team as collaborator (default team is `backend-devs`)
* add rowi1de/auto-assign-review-teams@v1.1.3 to add-to-project workflow

## Related Issues

Fixes #38

## Checklist

note.

- [x] I have added appropriate tests or updated existing tests.
- [ ] I have tested these changes on a dedicated VM or a customer VM
