Fix test_stable GHA workflow

[Balandat]

We do some grepping magic to extract the versions from botorch.egg-info/requires.txt after running python setup.py egg_info. This was not properly working when pinning a version to an exact match. This fixes that by allowing both >= and == version specification in the grep rexexp.
