"As a Curator, I want to know if a revision is marked as minor, so I can decide whether it needs review for content."
Contributors can voluntarily mark revisions as minor; it has different meanings for different wiki projects.
The schema for T231338 Page History API didn't include the minor flag for revision objects, which makes user stories like T234941 and T235572 harder to use.
For this user story, we need to add the minor flag to the output of GET /revision/{id}/bare, as defined in T231345.
