Fixing issue with invalid certificate test

[alecharp]

Testing done

The test GitLabConnectionConfigSSLTest is failing in BOM (jenkinsci/bom#5931) but also locally on the current master branch.
This is to fix it.

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

@krisstern as this is possibly blocking BOM release later this week.

Ok so there is more to it as Windows build still has the previous message.

Original test passes on Java 17 but not 21/25.
Patch is fixing Java 21/25 but breaks 17. Working on it.

Sorry for the force push, I didn't want to do yet-another-spotless-fix-commit.

LGTM

Thanks so much @alecharp!

@krisstern the plugin BOM test will continue to fail on this test until a new plugin release has been created that includes this fix. Are you available to create the plugin release or would you prefer that I create the plugin release?
