Describe the bug

az resource threw a bunch of errors. Even if "ls" isn't a valid option, it shouldn't be doing this and it makes me worry about using this at all.

Command Name
az resource ls

Errors:

    Triage finding

    az resource ls is not a registered Azure CLI command. The resource command table registers az resource list, so the final ls is misspelled or not recognized message is the invalid-command error. Use az resource list to list resources.

    The preceding SyntaxWarning messages are separate from that error: the paths in the output point to installed azure.batch and azure.mgmt.resource.deploymentstacks SDK model files, and the warnings identify invalid escape sequences under Python 3.14. They do not indicate that a resource operation was attempted or failed. The actionable cleanup is in those SDK dependencies' Python 3.14 compatibility, not an az resource ls implementation. There is no evidence here of an Azure resource command failure with the supported list subcommand.

    The resource command is az resource list, not az resource ls; the latter's “'ls' is misspelled or not recognized” error is expected. The resource command registration defines list but not ls.

    The preceding SyntaxWarning lines are separate: their paths point to installed azure.batch and azure.mgmt.resource.deploymentstacks SDK model files being parsed by Python 3.14, not to a failed resource operation. Please use az resource list for the intended command. The SDK warnings are still worth tracking independently for Python 3.14 compatibility; if they also appear with a valid CLI command, a separate issue with the warning paths and your CLI/Python versions would let maintainers investigate them without conflating them with the expected unknown-command error.

    Reproduced on 2.91.0 but gives a meaningful error on 2.89.0. Might be a regression in between.
