feat(RELEASE-1191): differentiate pyxis and umb in signing

[johnbieren]

This commit modifies the tasks used in simple-signing-pipeline to use separate credentials for Pyxis and UMB authentication. Prior to this commit, both were pulled from the same configMap values so it was impossible to use stage for one system and prod for the other.

This PR is ready for review. It is in draft status because I don't want to merge it yet. I don't want to put it in the same promotion cycle as #723

Great stuff!

/retest

[johnbieren]

E2E is failing here because it uses the simple-signing-pipeline on the stage cluster. This pipeline definition has task git resolvers, but it does not pass the new parameters to the tasks because it is the old pipeline definition, not the one from this PR. That is because IRs don't use git resolvers (yet) for executing pipelineRuns. So, I'd have to change the simple-signing-pipeline first, merge it, then run e2e for this PR. That should work, but it has to be part of the same promotion cycle or we will run into issues

Depends on #734

[mmalina]

I see you rebased this already (on top of merged #734 ). Shall I review it now? Let me know.

Yeah I think it should be good to go
