MGMT-19381: Change downstream base images to rhel9.4 instead of ubi9

[giladravid16]

Currently our base images use ubi9 and MintMaker wants to upgrade it to 9.5, because MintMaker looks at the repo and tries to upgrade to the newest tag.
This changes the base image to use a repo that is just for rhel9.4.
