Use proper syntax for only locking ZarrArchive table

[danlamanna]

From https://docs.djangoproject.com/en/4.1/ref/models/querysets/#select-for-update

By default, select_for_update() locks all rows that are selected by the query. For example, rows of related objects specified in select_related() are locked in addition to rows of the queryset’s model. If this isn’t desired, specify the related objects you want to lock in select_for_update(of=(...)) using the same fields syntax as select_related(). Use the value 'self' to refer to the queryset’s model.
