[Role] BREAKING CHANGE: az ad sp create-for-rbac: Drop name property from the output

[jiasli]

#18312 announced the deprecation of name. It is time to drop name property completely.

This eliminates the inconsistency between input parameter --name and output name property.

The output includes credentials that you must protect. Be sure that you do not include these credentials in your code or check the credentials into your source control. For more information, see https://aka.ms/azadsp-cli
