Automatically Assign Reviewers to Pull Requests

[Horiodino]

Describe the problem
Currently, contributors have to manually request reviews on their pull requests. This often leads to delays because reviewers are not automatically notified, slowing down the overall execution and merging process. Both reviewers and contributors lose time waiting for someone to notice the PR.

Suggested approach
We can integrate an existing GitHub Action that automatically assigns reviewers:
