Universal Developer Image enhancements
Is your enhancement related to a problem? Please describe
Issues related to Developers images
- gh action publishes the wrong "universal base image"
- there is not automated check for new versions the tools
- they are not compatible with Red Hat internal image build tool
- they are not multi-arch
- there is no PR check against Che samples
- manual modification of the README.md (tools lists and sizes) is tedious and error prone
Describe the solution you'd like
- #20798
- #20862
- #22029
- #20858
- Migrate to UBI9
- Automate developers image updates (c.f. dependabot ecosystem, renovate data sources)
- Add developers images PR check that validate che samples work
- Add developers images PR check that does a security scan (c.f. trivy)
- Automate certs injections in the Java keystore
- Automatically update developers images README
- #22009
- #22010

Rework developers images to make them compatible with Red Hat internal image build tool (aka brew)
Note: downstream in https://issues.redhat.com/browse/CRW-2463 and https://issues.redhat.com/browse/CRW-2464 we are required to have 3 images:
- udi for tech preview support
- udi for GA support w/ openjdk
- udi for GA support w/ openj9
Or, we need a way to differentiate which devfile tiles in the dashboard are GA-supported / tech-preview. Perhaps a red outline or a ribbon on the tiles? Could also use this mechanism to differentiate Che samples from CRW samples.
Please consider adding here the following issue as a sub-task: https://github.com/eclipse/che/issues/21253 .
Or, we need a way to differentiate which devfile tiles in the dashboard are GA-supported / tech-preview. Perhaps a red outline or a ribbon on the tiles? Could also use this mechanism to differentiate Che samples from CRW samples.
We now have a way of labelling devfiles as "tech preview" or "community" via a label.

udi for GA support w/ openj9
And there's no longer openJ9 images downstream (https://issues.redhat.com/browse/CRW-3048).
So, at this point we could consider having the same devspaces-samples projects in both Che and Dev Spaces, augmented by some projects that are ONLY upstream.
This would reduce the sample list so we don't have slightly different samples for the same languages in up vs. down, and would make it more feasible to use the same (or a more-closely-aligned, less-forking-needed) UDI image in both up and downstream.
