domains update failure

[mk]

I broke book.clerk.vision by trying to update it:

mk@mkair ~/d/book-of-clerk (main)> garden domains update --env production book.clerk.vision
Warning: Permanently added '172.16.227.70' (ED25519) to the list of known hosts.
Failed to get newest revision for branch

Was able to restore it by running

mk@mkair ~/d/book-of-clerk (main)> garden domains remove --env production book.clerk.vision
Warning: Permanently added '172.16.227.70' (ED25519) to the list of known hosts.
mk@mkair ~/d/book-of-clerk (main)> garden domains add --env production book.clerk.vision https://github.clerk.garden/nextjournal/book-of-clerk/commit/7097b690e91a3c5297db604546f8b538eef2f97f/
Warning: Permanently added '172.16.227.70' (ED25519) to the list of known hosts.

Would be good to fix this properly.
