CI: Check in the CI that assert_raises_regex is not being used
Follow up of #23592.

As `assert_raises_regex`is now deprecated, add to the CI a check to fail if a PR uses it.

@datapythonista : That's not true.  `assert_raises_regex` is [deprecated](https://github.com/pandas-dev/pandas/blob/58a59bd606911f11a4f679df18a00cfc25536c30/pandas/util/testing.py#L2576).  That's why I was saying that the need to check for usage was unnecessary.  Warnings will be issued if used. We still need the check, in case it’s used in a test that’s skipped on the numpydev job.

@datapythonista<https://github.com/datapythonista> : That's not correct. assert_raises_regex is deprecated<https://github.com/pandas-dev/pandas/blob/58a59bd606911f11a4f679df18a00cfc25536c30/pandas/util/testing.py#L2576>. That's why I was saying that the need to check for usage was unnecessary.

 I meant `now` instead of `not`.

I don't understand what you mean, sorry. I think after all your work replacing `assert_raises_regex` by `pytest.raises` now we don't want anyone to use `assert_raises_regex` anymore, right?

If you agree with that, this PR what it does it just to fail the CI if anyone uses it in a PR. Doesn't this make sense?

 lgtm merge on green  you need ``--includes '.py --includes '*.pyx''`` in your grep

```
Check that the deprecated `assert_raises_regex` is not used (`pytest.raises(match=pattern)` should be used instead)
Binary file pandas/tests/util/__pycache__/test_testing.cpython-36-PYTEST.pyc matches
Binary file pandas/util/__pycache__/testing.cpython-36.pyc matches
Binary file pandas/util/__pycache__/testing.cpython-36.opt-2.pyc matches
Check that the deprecated `assert_raises_regex` is not used (`pytest.raises(match=pattern)` should be used instead) DONE
``` I just did `--exclude=.pyc`. I don't think it should be used in `.pyx` or others, but I guess it's saver. Do you think `--include=*.py` is better? @datapythonista that's ok as well. I kind of slightly prefer the includes but prob doesn't make much difference here. ping on green. # [Codecov](https://codecov.io/gh/pandas-dev/pandas/pull/23627?src=pr&el=h1) Report
