Get Group Member has a 403 Error

[StarLight-Oliver]

The end point "/groups/{groupId}/members/{userId}"
is capable of getting a 403 error when the logged in user is not in that group.

HTTP response body: {"error":{"message":"You're not a member․","status_code":403}}

I this instead:
{"error":{"message":"You're not allowed to view membership details․","status_code":403}}
