ci: rebuild the OS package upgrade step weekly - #53
Conversation
The apt-get/apk upgrade step was served from the GitHub Actions build cache for as long as the base image digest and the RUN line stayed the same. So fixed Debian and Alpine packages never reached the image, and Grype failed every PR until the cache was deleted by hand. Pass the ISO week as OS_UPDATES_WEEK and use it in that step, so it misses the cache once a week. The other cached layers are kept.

- Around line 147-149: Update the workflow schedule to run weekly and adjust the
build-job condition so scheduled runs bypass the registry activity gate while
other triggers still honor it. Locate the schedule and
`needs.check-activity.outputs.should_run` condition in the workflow.

Summary
Every Dockerfile runs
apt-get -y upgrade(orapk upgrade) to pick up security fixes that the base image doesn't have yet. With thetype=ghabuild cache, that step was reused for as long as the base image digest and theRUNline stayed the same. On #52, every Apache and Alpine job failed Grype on fixed OpenSSL, expat and pcre2 CVEs because the upgrade layer showed asCACHED. Deleting all the Actions caches fixed it, but only once.GitHub's cache retention setting doesn't help here. It removes entries that haven't been used for a number of days, and this cache is used on every build. The retention setting is also not available on this account.
