TST: Fix xfail for git component of pd.show_version tests on 32 bit builds

[mroeschke]

Two tests were xfailed in this PR that suddenly failed. #46842

[jbrockmendel]

spitballing: i wonder if we can record when xfail(strict=False) tests xpass to try to track down patterns in the relevant conditions

[mroeschke]

Yeah possibly we could have an automation flow that reads the test-data.xml and when there are xpasses in the logs we can write to an issue

These tests are also failing on pandas-wheels nightly linux builds https://dev.azure.com/pandas-dev/pandas-wheels/_build?definitionId=3&_a=summary

[simonjayhawkins]

skipped on pandas-wheels for now MacPython/pandas-wheels#182 so that nightly builds for Linux are uploaded to https://anaconda.org/scipy-wheels-nightly/pandas/files

[lithomas1]

Marking as blocker for release. The wheel filenames will be messed up if this is not fixed(this may prevent pypi uploads).

Thanks @lithomas1 the nightlies did upload but the the wrong prefix pandas-0+unknown- instead of pandas-1.5.0.dev0+849.g3bf2cb1b22- so were probably of no use. (we may need to delete these from the server)

@simonjayhawkins Can you do this? I have no permissions whatsoever outside of this repo.

Nightlies are sadly still broken.
On Windows, the failures are because tzdata is a required dependency when testing, because of a bug here.

pandas/pandas/conftest.py

Lines 1219 to 1220 in 259a15c

	if zoneinfo is not None:
	TIMEZONES.extend([zoneinfo.ZoneInfo("US/Pacific"), zoneinfo.ZoneInfo("UTC")])

We need to create a dummy ZoneInfo object and check to see if that works as zoneinfo will not raise if tzdata is missing on import, only when creating the ZoneInfo object.

tzdata should also probably be added to the optional dependencies list in the docs and in pandas/compat/_optional.py.
I dunno which minimum version we should support though.
