CI: Test against newer version of MacOS (remove hack)

[gundalow]

SUMMARY

Currently, this collection is testing against an old version of MacOS which requires this hack

community.crypto/tests/utils/shippable/shippable.sh

Lines 62 to 69 in 52f7f02

	# START: HACK
	if [ "${script}" == "osx" ] && [ "${ansible_version}" == "2.9" ]; then
	# Make sure that the latest versions of pyOpenSSL and cryptography will be installed on macOS before
	# ansible-playbook is started. This is no longer necessary for devel (https://github.com/ansible/ansible/issues/68701
	# is fixed), but 2.9 still needs this since the new collection loader probably won't get backported to stable-2.9.
	sed -i -e 's/cryptography.*/cryptography >= 2.9.2/g' /root/venv/lib/python2.7/site-packages/ansible_test/_data/requirements/integration.txt
	echo 'pyOpenSSL >= 19.1.0' >> /root/venv/lib/python2.7/site-packages/ansible_test/_data/requirements/integration.txt
	fi

If we move to a newer version of MacOS this shouldn't be required

This should be done once the move to Azure Pipelines (AZP) is complete #155

We test both against OSX and macOS, so I think we still need this hack.
