Creating a resource group shows no help and error message is not correct?

[StefH]

Problem description

When using C# to create a resource group, I got this error:

could not make instance of 'azure:storage/account:Account': name 'stef-storage-pulumi' plus 8 random chars is longer than maximum length 24

and when changing the name to stef-sa-pulumi, I get this error:

error: azure:storage/account:Account resource 'stef-sa-pulumi' has a problem: name ("stef-sa-pulumice35b767") can only consist of lowercase letters and numbers, and must be between 3 and 24 characters long

Issues

1. There is no way to find out what the restrictions are, please add this to the argument help.
