"review transcriptions" on org landing page for transcribed collections

[saracarl]

Org landing pages, like this one: https://fromthepage.com/khs may not have a "start transcribing" button on collections because they are transcribed already -- however, the collection may still need review. Perhaps a "review transcriptions" button that takes you to a random page in the collection to review is the right action then?
