in tests, change pd.arrays.SparseArray to SparseArray

[Dr-Irv]

• closes CLN: Deprecate pandas.SparseArray for pandas.arrays.SparseArray #30656 (comment)
• tests added / passed
  • modified most tests that use pd.arrays.SparseArray to just import SparseArray
• passes black pandas
• passes git diff upstream/master -u -- "*.py" | flake8 --diff
• whatsnew entry
  • N/A

For @jreback to review based on his comment previous PR #30656

In a few files (see below), left it as is because usage was pretty local (and allows pd.arrays.SparseArray reference to be tested in code)

$ grep -c -r arrays.SparseArray . | grep -v ":0"
./dtypes/test_generic.py:1
./frame/methods/test_quantile.py:2
./series/test_missing.py:2

My style preference is to just use pd.arrays namespace.

[Dr-Irv]

My style preference is to just use pd.arrays namespace.

So in the various test modules,
So @TomAugspurger prefers to use pd.arrays.SparseArray, i.e., writing pd.arrays.SparseArray([1,2,3]) in a test.
And @jreback prefers to from pd.arrays import SparseArray, i.e., writing SparseArray([1,2,3]) in a test

I did the latter because of feedback from @jreback , so you guys need to work out your differences.

[TomAugspurger]

Yep, that's what we're doing.

this looks fine to me, i slightly prefer the shorter syntax. unless @TomAugspurger objects, ok to merge this.

[TomAugspurger]

No objections.
