test_shell_error() doesn't catch the right regex on macOS in zsh

[drewbrew]

Hey, I'm not sure whether macOS or zsh is at fault here, but if you run tox on macOS, the test_shell_error() test fails to match the regex:

tox -e py311-dj41-sqlite
# snip
.tox/py311-dj41-sqlite/lib/python3.11/site-packages/django_migrations_ci/shell.py:23: MigrateCIShellException

During handling of the above exception, another exception occurred:

    def test_shell_error():
>       with pytest.raises(shell.MigrateCIShellException, match="/bin/sh: 1: oof: not found\n"):
E       AssertionError: Regex pattern did not match.
E        Regex: '/bin/sh: 1: oof: not found\n'
E        Input: '/bin/sh: oof: command not found\n'

tests/test_shell.py:12: AssertionError

Here's what I believe will fix it:

diff --git a/tests/test_shell.py b/tests/test_shell.py
index 56a14c7..d3a0765 100644

         shell.exec("oof")

If you think this is worth adding in, I'm happy to throw up a quick PR.

The exact message is not important, just have to check the command failed properly. Checking for something like oof.+not found is good enough.

I don't have a mac to try it, but I'd like to support it too. Please, PR! 🙏🏻
