Backport PR #43150: BUG: GroupBy.quantile fails with pd.NA

[jreback]

@debnathshoham

need to change the any_float_dtype fixtures as that is changed in 1.4 e.g. https://github.com/pandas-dev/pandas/pull/43408/checks?check_run_id=3515311784

and update the PR to this branch

[debnathshoham]

Will have to change any_int_ea_dtype to any_nullable_int_dtype, and any_float_dtype to any_float_allowed_nullable_dtype.
Again, since not my PR will need help from maintainer.

Little confused why test_groupby_quantile_allNA_column is failing though

@debnathshoham you can fork this PR and create a new one (or I can do it.. LMK)

[debnathshoham]

hi @simonjayhawkins - not sure how to fork this PR (didn't get anything on google; can try if you can point me to something that explains how to do it).
Or, are you suggesting I fork the 1.3.x branch?

[simonjayhawkins]

There's an "open with" button in the top right next to the issue title. (if using github through the web)
