ConflictException: PermissionSet with name AdministratorAccess already exists

Hello,

After running this for the first time it creates the resources as expected.

I now create an AWS member account via aws organizations, I would have expected to be able to re-use existing SSO permission set AdministratorAccess as per AWS documentation: https://docs.aws.amazon.com/singlesignon/latest/userguide/permissionsets.html?icmpid=docs_sso_console

When permission_sets is removed then the module fails as I can see it's required

Terraform v1.1.7
