Add jdk.net module for Java 25

I cannot confirm it will fix one of the issue I discovered running Jenkins on Java 25

Testing done

None. I cannot confirm it will resolve the issue.

But I will certainly test in on my test environment and iterate if needed

Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests that demonstrate the feature works or the issue is fixed

Can you (at least) run make test on a local image, and test it in your environment (nice to have) please?

Having an dedicated additional test in ./tests/ would be nice to have too.

We can help you if you need, just let us know 🙂

@jonesbusy could you mind open a dedicated issue describing the error you found please?

That would be helpful as reference for this PR and #1124, and easier for you to add details if you're the author of that issue.

Suggesting to wait for #1128 (if accepted) to include this change 🙂

[lemeurherve]

@jonesbusy FYI I'll resume the work on #1132 and #1128 soon so you can progress on this.

Seems like some tech debt from #201. TBH I am not sure how this was ever safe. What is some plugin sends a ControllerToAgentCallable which requires one of the Java modules that was not bundled?
