Fix problems for split packages that have different signing certifacts

[merks]

Since yesterday there is a new signing certificate available so I'm creating this blanket issue which is just like this previous issue to record the problems and their resolutions:

https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/issues/2335

I have this build that tests for split packages with inconsistent signatures:

https://ci.eclipse.org/oomph/job/repository-analyzer/lastBuild/

It produces this report:

https://download.eclipse.org/oomph/archive/reports/download.eclipse.org/eclipse/updates/4.37-I-builds/index.html

Its best to look at the latest one, currently this:

https://download.eclipse.org/oomph/archive/reports/download.eclipse.org/eclipse/updates/4.37-I-builds/https___download.eclipse.org_eclipse_updates_4.37-I-builds_I20250718-0410.html

We can see that we have 81 split packages 9 of which have become inconsistent:

These are the same test failures reported in the build:

In each case I will need to force a qualifier change in the one with the older certificate which expires July 21st.
