The 3 test failures can be fixed by upgrading from pandas-2.2.2 to pandas-2.2.3. The 327 errors are due to missing of dependency pyqt. Given that this package is not a marquee package in SDM images, we should disable such tests that require this dependency.

After the above changes, all tests passed:

200970 passed, 21732 skipped, 1971 xfailed, 88 xpassed, 26 warnings in 376.44s (0:06:16)

Note: You can still install pyqt as part of the test dockerfile and run those tests. Our goal is to ensure that all features of Pandas are working correctly (even if it has optional dependencies)
