Revert "TST: Bare pytest raises" in base extension tests
Reverts pandas-dev/pandas#38576, see discussion there. We should not add detailed error message asserts, as those tests are also used by external packages, that might have different error messages.
@MarcoGorelli on the PR you mentioned "` ^pandas/tests/extension/` excluded from when the "disallow bare pytest raises" will be applied to CI"; but so I understand it correctly: at the moment we don't yet test it in CI? (it seems "bare_pytest_raises" validation type is not yet used in practice). So this is not yet actionable right now? > So this is not yet actionable right now?

Yes, that's right - I was just asking about what should be done in the future about these tests once it is checked in CI.

Also, does `pandas/tests/arrays/boolean/test_arithmetic.py` need to be reverted too? I don't have a strong preference. I can also add `match=None`, whatever you prefer thanks @jorisvandenbossche
