nightly failing because it cannot find tzdata

See https://github.com/pandas-dev/pandas-stubs/actions/runs/4438156563/jobs/7789166798

nightly run is failing because it can't find tzdata >= 22.1, but that doesn't make sense as version 22.7 is available.

@twoertwein can you take a look?

Re-running the job didn't fix it :(

I tried to re-create the issue locally but in my python 3.11 environment everything works fine. I'll create a PR bumping the two nightly runs to 3.11 - maybe it fixes it (maybe not) but it anyways doesn't hurt to use the newest pythn version for the two nightly tests.

reopening as I merged a PR, and the fix in #582 didn't work. Can you take a look @twoertwein ?

The CI runs python -m pip install --use-deprecated=legacy-resolver --upgrade --index-url https://pypi.anaconda.org/scipy-wheels-nightly/simple pandas and that also fails for me locally.

If I use python -m pip install --upgrade --index-url https://pypi.anaconda.org/scipy-wheels-nightly/simple pandas it works! I will try to go back to the old PR adding that to see why we use the legacy resolver (edit: #238 (comment)).

edit: the above did not actually upgrade pandas... not even when adding --pre --upgrade-strategy eager.
