keycloak: Fix typo in swh-web client role

I noticed that the users to which I manually added the swh.web.api.throttling_exempted permission do not have it anymore since the configuration update in !67 (closed).

Turns out I made a typo in the permission name and thus the permission with correct name was removed by puppet. My bad, I should have double checked.
