* Add HTTP 403 to possible profile responses
Some servers may not allow profile lookup over federation, and thus
respond to GET /_matrix/client/v3/profile/{userId} with an HTTP 403.
For example, Synapse can be configured to behave in this way by setting:
allow_profile_lookup_over_federation=false
Thus, this behavior already exists in the wild, and may cause issues for
clients such as https://github.com/vector-im/element-web/issues/17269.
Synapse could alter its behavior and return an HTTP 404 in these cases,
but amending the Spec seems preferable to align with extant behavior.
Further, allowing HTTP 403 gives clients more specific information as to
why a request has failed, enabling more precise error handling.
