Batch-add "performance of" relationships should add an edit note

https://musicbrainz.org/edit/49586656#note-49586656-2 These edits should allow edit note by the editor (I don’t know if it already does) but should anyway always add an edit note footer saying that this edit was created by Batch-add "performance of" relationships so it could hint the future editors of the relatively poor trust value of those global/broad slightly blind edits, compared with manual edit, based on a specific release.

Second this, there needs to be an edit note
