Please port to Python3.12

Describe the bug

The test suite does not pass when using Python3.12 as it is reported in a Debian bug report. It results in

E       AttributeError: 'TestApplication' object has no attribute 'assertNotEquals'. Did you mean: 'assertNotEqual'?
tests_core/test_application.py:56: AttributeError
E       AttributeError: 'TestApplication' object has no attribute 'assertNotEquals'. Did you mean: 'assertNotEqual'?
tests_core/test_application.py:35: AttributeError
E           AttributeError: 'TestCommandRegistration' object has no attribute 'assertDictContainsSubset'
tests_core/test_command_registration.py:96: AttributeError
E           AttributeError: 'TestCommandRegistration' object has no attribute 'assertDictContainsSubset'
tests_core/test_command_registration.py:564: AttributeError

While fixing the assertNotEquals can be easily fixed with this patch assertDictContainsSubset is not supported any more as you can read in the Python3.12 documentation.
(BTW, the patch is against the Debian packaged version 2.50.0 so not the latest release but it should be pretty easy to adapt sind the replacement is simple.)

Related command

Simply run the test suite under Python3.12.

Hi @tillea,

2.50.0 is not the latest Azure CLI(2.56.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

Hi @tillea,

2.50.0 is not the latest Azure CLI(2.56.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

I'm perfectly aware that this is not the latest version. However, I've seeked for the string assertNotEquals inside the Github web interface and found the according hits so I expect the problem to persists even in the latest release.

Kind regards, Andreas.
