Trello integration action

The action scans PR description, comments and branch name for Trello cards. When found, it seamlessly integrates GitHub with Trello:

• Links a PR to a Trello card and vice versa (works best with GitHub Power-up).
• Moves the Trello card when a PR is opened or closed.
• Applies an appropriate board label to a Trello card based on the branch name categorization (e.g., feature/foo).
• Assigns the PR author and fellow assignees to the Trello card.
• And more...
