Publish to INBUXA's own image, and don't release on a schedule yet

Two things inherited from public ihasmail that became live the moment this
repository went public.

publish.yml pushed ghcr.io/coffey-labs/ihasmail -- the image every public
ihasmail install pulls. A release here would have published INBUXA's webmail
over it, which is the exact confusion SPEC 5 exists to prevent. It now
publishes ghcr.io/inbuxa/ihasmail-inbuxa.

release.yml cuts a release every Monday at 09:17 UTC, which public ihasmail
wants because it has users expecting one. This fork has none yet, and the
release triggers the publish, so on Monday it would have shipped an image
and mailed everyone watching about a product that has not shipped. Scheduled
runs now stop at the first job; a release can still be cut by hand, and the
weekly one comes back by removing one line.
