fix api docs routing clash with /api

/api-docs was getting routed to the backend /api route. The
documentation at https://kubernetes.io/docs/concepts/services-networking/ingress/
describes that the path should match on the full element so this was
unexpected. Adding a trailing slash is not supposed to have an impact
but in this case it solved the problem.
