Remove flaky queue resizing tests

The min and max queue resizing tests sometimes fail due to timing
issues. Since the queue resizing is already removed for 8.0 (elastic#52280),
there is less incentive to debug the flakiness. Given there are some
other tests of queue resizing, and the feature is already removed in
upcoming versions of ES, this commit removes the flaky tests.

closes elastic#71476
