fix test for github milestone_url

[ReimarBauer]

The current test checks for closed issues matching a version in the URL search string (e.g., https://github.com/Open-MSS/MSS/issues?q=is%3Aclosed+milestone%3A10.0.1). This approach incorrectly returns ‘True’ even if the version doesn't exist.

Instead, we could verify a release exists by checking for a 200 status code when requesting its tag (e.g., https://github.com/Open-MSS/MSS/releases/tag/10.1.0). That fails because the version string is updated before the corresponding tag is created.

I think we should remove the test.

The syntax on the page has changed.

https://github.com/Open-MSS/MSS/releases/tag/10.2.0#target

The pattern https://github.com/Open-MSS/MSS/pull/2824/files#diff-6699ce6791f91adc6e8b9668895126834cfc9eff3a279536ded4ce49c9a787c4L92

needs to be fixed or how we retrieve the content.

We want a verification by the test that when someone clicks on the about url that he can get informations.
