Move Test and Example projects transitively requiring Java-25 to Java-25

[HannesWell]

This reduces warnings in the workspace (like Execution environment is lower than one of the plug-in's dependencies (org.eclipse.core.filesystem) which has an execution environment of JavaSE-25) and simplifies launching tests as plain Junit test.

In general we migrate to higher EE requirements only on demand and don't to mass moves, but for Tests and examples I'd say that acceptable.

This pull request changes some projects for the first time in this development cycle.
Therefore the following files need a version increment:

examples/org.eclipse.ui.examples.javaeditor/META-INF/MANIFEST.MF
examples/org.eclipse.ui.genericeditor.examples/META-INF/MANIFEST.MF

An additional commit containing all the necessary changes was pushed to the top of this PR's branch. To obtain these changes (for example if you want to push more changes) either fetch from your fork or apply the git patch.
