update wiki page meta: %w

Error message

update wiki page meta: %w

What it means

UpdatePage wraps the repo failure from UpdateWithRevision, which atomically snapshots the superseded version and writes the new page content. The update (and its revision snapshot) is rolled back as a unit, so no partial history is left behind.
