fix UI for group curated list editing

When creating or editing a list, the group selection dropdown will only appear if the user selects "group" as the curation option (or it is already selected).

- fix typo in bookwyrm.js comments
- add data-hides trigger for hiding elements after they have been unhidden, where simple toggles are not the right approach
