Upgrade JaCoCo plugin for JDK 17 compatibility (#2033)

[HeVictor]

This PR aims to solve #2033 by bumping JaCoCo plugin to 0.8.8, as attempting to run mvn clean install on the design modules under JDK 17 with the current version will result in the java.lang.IllegalArgumentException: Unsupported class file major version 61 error.

For testing I've ran an overall mvn clean install on the entire project under JDK 17 with source and target also set to 17 in the pom.xml, and only the naked-objects pattern module produced an error (although there were warnings with other modules). It looks like the problem is rooted in an error running the Datanucleus enhancer inside dom (not much more error info) and errors inside integtests with using versions of the Cucumber library that's also too old from the Apache Isis dependency. I've tinkered with it a lot by updating dependencies and plugins inside naked-objects and still couldn't solve the errors, which is why I'm making this PR a draft.

I see there have already been discussions with naked-objects having some problems and being outdated from #1683 and #1669, and I'm happy to try rewrite the naked-objects to be more up-to-date and see if it can work with JDK 17 then. If it's crucial to have naked-objects build without errors under JDK 17 I'm happy to keep this PR in draft until the refactor is done.

Thanks @HeVictor for looking into this. I think this change is safe to merge as it doesn't break anything in master.
