Description

On 6/4, pytest released a new version == 8.2.2, which caused several of the E2E and unit tests to fail with an AssertionError "assert testcase is not None". This changes to install a compatible version of pytest. 7.4.4 is the latest version we can pin to, as the 8.* versions are not supported in python 3.7.

For example:

• E2E tests: https://github.com/Azure/azure-functions-python-worker/actions/runs/9413740604/job/25931135947
• Unit tests: https://github.com/Azure/azure-functions-python-worker/actions/runs/9397259034/job/25880092469
