skip GitPython 3.1.28, since it prints 'git' as version which messes up the version check in check_github()

[boegel]

Temporary workaround for hard crash when running eb --check-github:

Checking status of GitHub integration...

Making sure we're online...OK

* GitHub user...easybuild_test => OK
* GitHub token...(no token found) => FAIL
* git command...OK ("git version 2.37.3; ")
* GitPython module...OK (GitPython version git)

I've reported this problem upstream at gitpython-developers/GitPython#1500 .

Regardless, we should probably make the code in check_github() a bit more robust, in case we're hitting a non-digit GitPython version...
