### What changes were proposed in this pull request?
This PR proposes to fix and reenable `test_stats_on_non_numeric_columns_should_be_discarded_if_numeric_only_is_true` that was disabled when we upgrade Python 3.9 in CI at https://github.com/apache/spark/pull/32657.
Seems like this is because of the latest NumPy's behaviour change, see also `https://github.com/numpy/numpy/pull/16273#discussion_r641264085`.
pandas inherits this behaviour but it doesn't make sense when `numeric_only` is set to `True` in pandas. I will track and follow the status of the issue between pandas and NumPy.
For the time being, I propose to exclude boolean case alone in percentile/quartile test case
### Why are the changes needed?
To keep the test coverage.
### Does this PR introduce _any_ user-facing change?
No, test-only.
### How was this patch tested?
I roughly locally tested. But it should pass in CI.
Closes#32690 from HyukjinKwon/SPARK-35510.
