I noticed we weren't getting updates and I think the
core problem here is renovate was only triggering on
the devel compose. But we just "floated" to whatever
was found in the production compose as a base.
Also we had a random copr.
Drop that stuff, and just pin on the production compose.
In order to streamline the focus, let's drop fedora-bootc:eln.
- We want to be moving container builds into upstream distributions anyways
- Building two containers from one git repository is awkward in Tekton
- It's not worth shipping around a distinct build container;
bootc-image-builder already has all the dependencies we need
since 44d15acded
- I'd like to add a more first-class mechanism in bib to build
base images
