Enable url links to tests results.

### What feature do you want to see added?

It will be great when jUnit support url links.
POV we import results after every suite. It helps to get job health quickly. (~400 suites, 120K testcases, ~ 1milion assertions can take a while)
After every suite we archive all failed projects ( this is not maven things), logs, crash dumps ...
It will be really great when jUnit function support links to URLs like option ``` url : [ [link : 'https://..../artifacts', text : 'Artifacts'] ```
Or for security reasons enable only relative URLs to jenkins. This will help the user to navigate from test case to real log, configs ...

When you allow also external URLs we can point suite results to source code management too.

Or whatever the user want.

Oh I forgot. The links should be shown in sidebar when I navigate to suite results

### Upstream changes

_No response_

The issue names JUnit result importing and the suite-results sidebar, but no files or tests. Start by locating those entry points and determine how archived artifacts and security restrictions should be represented; done means users can navigate from suite results to configured artifact or other permitted URLs.
