[CHORE] Modify /registry/score/{scorer_id}/{address} and /registry/score/{scorer_id} to accept strings for scorer_id

[tim-schultz]

Follow up to passportxyz/passport#1041

1041 added the ability to create a scorer with an external id. The /registry/score/{scorer_id}/{address} and /registry/score/{scorer_id} endpoints should be modified so that they can accept a string or an integer for scorer_id.

The query to retrieve to retrieve a scorer by id or external_scorer_id should already be satisfied with

def get_scorer_by_id(scorer_id: int | str, account: Account) -> Community:
    try:
        return Community.objects.get(external_scorer_id=scorer_id, account=account)
    except Exception:
        return api_get_object_or_404(Community, id=scorer_id, account=account)

This ticket should just update the endpoint parameter type
