Start the weekly release (#3)

The schedule has been off since the fork was cut, with the check job
gated to workflow_dispatch so a release could only be cut by hand. The
reason was that a scheduled release publishes an image and mails
everyone watching the repository, and there was nothing yet to tell
them about.

INBUXA is releasing now, so the gate comes off: Mondays at 09:17 UTC,
and nothing on a quiet week, which is what the workflow already decides
for itself. Cutting one by hand still works and is unchanged.

This restores the file to public ihasmail's, byte for byte -- the gate
and the note explaining it were the only difference.

Two things worth knowing before the first one runs. GHCR creates a
package private the first time, even in a public repository, and no
workflow can change that: the first release will publish an image that
an anonymous `docker pull` refuses until the visibility is set by hand
under the package's settings. And GitHub disables scheduled workflows
in a repository with no activity for 60 days, so a silent stop later is
worth checking for before assuming the file is broken.
