CI: Bump timeouts Python dev builds
e.g. https://github.com/pandas-dev/pandas/actions/runs/3193038414/jobs/5211185245

I just ran the tests (--skip-slow --skip-db) from April 1 and they took 19:30, compared to 30:06 from yesterday.  Of that half hour, 8 minutes is in tests/extension/test_arrow.py.  Not sure what to do with this, just making sure its written down. (FWIW: The Python dev builds don't run the optional deps)

Each test in `extensions/test_arrow.py` is essentially parameterized over 37 pyarrow dtypes (plus want to test list and struct support in the future to defer nested data support to pyarrow). There may be areas where skips per dtypes is possible, but otherwise the tests are very thorough (and long) because of this. I think the main issue is the build step. Building pandas shouldn't take 25 minutes like it does on the macOS job. At least this gives us a buffer (other builds are at 120)

@lithomas1 any quick suggestions how we might speed things up or should that be addressed in a followup?

 Try changing this line https://github.com/pandas-dev/pandas/pull/48973/files#diff-f6f33d5fc5cfd739f0d6efd63ea9dff886abe35cdfff5672e9a863ec8da8e72cR78 to 
``python -m pip install -i https://pypi.anaconda.org/scipy-wheels-nightly/simple numpy``

Numpy should be uploading Python 3.11 wheels so, we'll shave off ~5 minutes for sure from not compiling numpy. We might get a little more speed-up in the tests too from this.
