Remove dual scopes from Notification template api access controls

[RushanNanayakkara]

Proposed changes in this pull request

The added configuration of two scopes for the same endpoint is wrong and is not currently supported. This PR fixes that by removing the old scope from the previous email template management API and keeps the new scope configuration.
This also places the notification template management API(NTM) access control definitions above email template management API(ETM) access control definitions since the ETM API access control definition regex pattern could match the NTM API access control definitions, resulting in the NTM requiring the ETM scopes to function.
