Message:

Revisions: Remove unused post meta data during database upgrade.

Introduced in [23811], WordPress displayed some additional information for restored revisions for a short period of time. This was removed again in [25194], but the meta data was still being saved unnecessarily.

After 3 years and no plugins ever using this meta data, it's time to stop collecting it.

Fixes #36526.
