Remove identity center auth manager cli (#42481)

* Remove identity center auth manager cli

The CLI command to setup identity center could only setup part of the
required resources, since adding an application must be done from the
console. As of November 15, 2023 it is now required to have an
AWS Organization setup to create the required type of Identity Center
Instance. The script would have to be change majorly to achieve this but
it is also something that should be done with great care and intention
since creating an organization in your AWS account has implications. If
we automate it, many users won't know it's being created. Instead have
users run through the wizard provided in the AWS console.

* Missing test change
