[williamhbell]

az feedback auto-generates most of the information requested below, as of CLI version 2.0.62

Describe the bug
The documentation https://docs.microsoft.com/en-us/cli/azure/ad/group?view=azure-cli-latest#az-ad-group-list states that az ad group list supports --subscription under the Global Parameters section. It does not support --subscription. The documentation should be corrected.

To Reproduce
Try az ad group list with --subscription.

Expected behavior
The flag is accepted or the documentation is changed.

Environment summary
Azure CLI version 2.34.1, MSI installed, Windows 10.
