--subscription flag not valid on az login

[samertm]

Describe the bug

az login will now prompt the user to pick a subscription, but it doesn't accept a --subscription flag to automatically pick a subscription. Our usecase is that we have a make init rule in a Makefile that sets a user's environment correctly that calls az login, and it's confusing users that they now need to select a subscription manually after running it.

This feature request of supporting --subscription by az login is tracked by #14933

You may disable interactive subscription selection following the instruction at #28910 (comment):

az config set core.login_experience_v2=off
az login

Probably worth documenting that in the interactive output of az login. Right now we run az login < /dev/null to avoid the interactive mode when our devs need to log into az.

We will include this command in the official document in MicrosoftDocs/azure-docs-cli#4326.
