Omit a broken https test on MinGW
This started to reliably fail on MinGW at an irrelevant commit: https://github.com/ruby/ruby/actions/runs/6981002841/job/18997302124 https://github.com/ruby/ruby/actions/runs/6981946473/job/19000104223 https://github.com/ruby/ruby/actions/runs/6983823136/job/19005613809 https://github.com/ruby/ruby/actions/runs/6983912116/job/19005844596 https://github.com/ruby/ruby/actions/runs/6984215921/job/19006649495 https://github.com/ruby/ruby/actions/runs/6984383103/job/19007100446 https://github.com/ruby/ruby/actions/runs/6986489509/job/19012000642
So this failure is not detecting a new bug. Let's skip this until we fix this test for MinGW.
