Maybe just use the non-minimal UBI as the builder? (unless you want to use one of the tricks from my other comment to avoid the separate builder image)

# For deployment, we need the following installed (they are installed # by default in RedHat UBI standard):
This comment could use an update.
Before: We were using ubi8/ubi because we hadn't figured out how to get tzdata into the ubi8/ubi-minimal image. Why: The ubi8/ubi-minimal image is smaller and now has everything we need. Now: The docker image is based on ubi8/ubi-minimal. The required tzdata files are acquired by rpm erasing the tzdata package and then reinstalling it (there is no `microdnf reinstall` command in the current image). Release note (backward-incompatible change): The docker image is now based on RedHat's ubi8/ubi-minimal image (instead of ubi8/ubi). This image is smaller.

I switched to using the rpm erase hack you noted in #54812.
