Describe the bug

Providing wildcard character as argument throws a strange error in Azure Cloud Shell (both powershell and bash shells).
This only happens in Cloud Shell. I'm not sure which CLI version introduced this regression, but we had a customer report this error recently in this github issue.

To Reproduce

az appconfig kv list -n test-appconfig-00 --key *
UnrecognizedArgumentError: unrecognized arguments: test.json
Try this: 'az appconfig kv list --label <test,prod,\0> --name '
Still stuck? Run 'az --help' to view all commands or go to 'https://aka.ms/cli_ref' to learn more

Commands that still parse wildcard as expected:

az appconfig kv list -n test-appconfig-00 --key *abc
[]

az appconfig kv list -n test-appconfig-00 --key abc*
[]

Workaround for parsing wildcard:

az appconfig kv list -n test-appconfig-00 --key "*"
[]

Expected behavior

Many AppConfig commands accept wildcard characters as input arguments. Parsing * without quotes should not throw any error.
