URL-encode links to tests

[basil]

Fixes #659

Testing done

• mvn clean verify
• Reproduced the problem described in the ticket in Firefox and 2.479.1 before this PR, could no longer reproduce after this PR
• Attempted but failed to write an automated test with HtmlUnit, as I could not reproduce the problem in HtmlUnit but could in Firefox

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 demonstrates feature works or fixes the issue

@jenkinsci/core-security-review Any objection to this? I can't think of a reason why URL-encoding the test name would be harmful, but maybe I'm missing something here.

Thanks to everyone who contributed to fixing this bug.

Links under 'All Tests' are now percent-encoded, but spaces are being replaced with + signs, which breaks the links. Manually replacing + with spaces or %20 makes them work again.

Meanwhile, links under 'All Failed Tests' are still preserving square brackets ([]) as-is.

NOTE: Previously, only square brackets were an issue, and spaces were preserved.

Thank you to everyone who worked on resolving this issue. I can confirm that the "All Tests" link now functions as expected, with all associated links working correctly.

However, links for individual failed test reports (All Failed Tests) are still encountering the original issue: square brackets in the URLs are not being replaced with percent-encodings, which still results in link failures. I've attached a screenshot for additional context:

Thank you for your continued efforts on this.

see #659 (comment)

[ahadalioglu]

As I understand it, there's nothing more that can be done regarding the last report, correct? Then we'll rely solely on the 'All Tests' section and avoid using the 'All Failed Tests' section.

Thank you very much, though.
I really appreciate your prompt assistance so far.

As requested previously, please file a separate ticket for any other places where the URL is not properly encoded, ideally with a PR that resolves the issue.
