Label when git conflicts

It can be tiresome to open a pull request and realize that it has Git conflicts.

Here's an example of a reviewpad.yml configuration file that labels pull requests that have Git conflicts.

api-version: reviewpad.com/v3.x

workflows:
  - name: handle-conflicts
    if:
      - $hasGitConflicts()
    then:
      - $addLabel("conflicts")
      - $comment("This pull request has merge conflicts. Please resolve them and then rebase on the base branch.")
