Incorrect info about the wildcard router

The document https://access.redhat.com/documentation/en-us/red_hat_3scale/2.1/html/infrastructure/onpremises-operations#apicast_built_in_wildcard_routing_tech_preview mentions the following:

API endpoints must end with the -staging or -production suffix (e.g. api1-production.example.com, api1-staging.example.com), If your API endpoints do not have one of these suffixes, calls will return a 500 error code.

Apparently this limitation does not apply to AMP 2.1 (it was for AMP 2.0).
