[operations/docker-images/production-images@master] Switch php7.4-cli to bullseye and cascade
Though mainly focused on supporting the php 8.1 migration, there's ongoing work to support multiple base-image “flavors” and a helm-release-to-flavor mapping in scap (T370934), which may be useful here.
Basically, as a pre-step for the migration to bullseye+8.1, we could use this to incrementally switch from buster+7.4 to bullseye+7.4. That would both (1) exercise the new functionality in scap before we try to apply it to the more complex migration and (2) de-risk the latter by separating the Debian release change from the php version change.
One implication of going that route is that we would (temporarily) need to maintain multiple 7.4 base image "stacks" in operations/docker-images/production-images (the existing one, plus a bullseye version).
