"""Open the next version line: VERSION_NAME_BASE plus everything pull-request.yml requires with it.

That is the AppStream <release> entry in metainfo.xml, its five <image> URLs moved to the
new version's release assets, and the Play what's-new rendered from the entry by
sync-play-changelog.py. The entry's paragraph is a placeholder; rewrite it and re-run
sync-play-changelog.py before the internal cut, or it ships as the store text.

Running it twice for the same version changes nothing the second time.
