Add GitHub Action to auto-assign Devin PRs to requesting users

Summary

Adds a lightweight GitHub Actions workflow that triggers when a PR is opened by devin-ai-integration[bot]. It parses the "Requested by" field from the PR description and assigns the PR to that GitHub user.

Supports both formats Devin uses:

• Requested by: @username
• Requested by: Full Name (@username)

If no requesting user is found in the body, it logs a message and does nothing.

Review & Testing Checklist for Human

• Regex coverage: Verify the regex handles all "Requested by" formats that Devin PRs actually use — spot-check a few recent Devin PR descriptions to confirm. Usernames with hyphens (e.g. @some-user) are supported, but other special characters are not.
• Permissions: Confirm that the GITHUB_TOKEN with pull-requests: write and issues: write is sufficient for addAssignees in this repo (private repos may have different default token scopes).
• Test plan: After merging, have Devin open a new PR and verify the assignee is automatically set. There is no way to test this workflow before it's live.

Notes

• This workflow is being added to elementary-internal, elementary, and dbt-data-reliability via separate PRs with identical content.
• No error handling around the addAssignees API call — if the user can't be assigned (e.g., not a collaborator), the workflow will fail visibly but won't block the PR.
