Add Maven Wrapper configured to use Maven 3.9.3.

• Ran mvn wrapper:wrapper -Dmaven=3.9.3 -Dtype=only-script
• Manually added SHA256
• Updated workflow to use wrapper

I'd forgotten the "linux" build workflow is now cross-platform, but seems Windows Powershell is working fine with that syntax anyway ..

LGTM

the maven wrapper script is actually pretty cool, it even uses a java single-file-program as fallback download option :)

@mbien yes, saw that - hadn't looked at the new script option until last week when adding mvnw to another project. Some interesting things in there, although with a few caveats for now. The Windows one might also be interesting to look at - I wonder if a batch to powershell launcher option could work for the IDE?

worth a try. Esp since old systems like win 7 are essentially gone now. I remember that starting programs via scripts on old windows systems had problems like not being able to close the command prompt or having it pop up for a split second etc. I bet those issues are solved by now - not sure.
