Overview of the Issue

Atlantis cannot apply when a failure occurs due to lack of apply_requirements, even if the requirements have been met after.
In this case, the mergeable requirement always fails because one of the apply jobs in the pipeline failed (apply without approvers).

VCS Details

• VCS: GitLab
• Project Settings:
  • Protected branches -> Code owner approval (main)
  • Merge requests -> Pipelines must succeed

Reproduction Steps

1. Run atlantis apply without approvers on the merge request
2. Expected error: Apply Failed: Pull request must be approved by at least one person other than the author before running apply.
3. Approve the merge request
4. Run apply again
5. Unexpected error: Apply Failed: Pull request must be mergeable before running apply.
6. Run plan
7. For any new apply on this MR: Apply Failed: Pull request must be mergeable before running apply.
