/**
 * CommitItem
 *
 * -----------------------------------------------------------------
 * WARNING: Please keep changes up-to-date with the following files:
 * - `views/projects/commits/_commit.html.haml`
 * -----------------------------------------------------------------
 *
 * This Component was cloned from a HAML view. For the time being they
 * coexist, but there is an issue to remove the duplication.
 * https://gitlab.com/gitlab-org/gitlab-foss/issues/51613
 *
 * EXCEPTION WARNING
 * 1. The commit navigation buttons (next neighbor, previous neighbor)
 *    are not duplicated because:
 *     - We don't have the same data available on the Rails side (yet,
 *        without backend work)
 *     - This Vue component should always be what's used when in the
 *        context of an MR diff, so the HAML should never have any idea
 *        about navigating among commits.
