[Override] gRPC logs rendering is not correct

[foxish]

It is showing these requests as HTTP when they are gRPC

signadot local override --sandbox pr-259-route -w route -p=8083 --with=localhost:8083
→ Applying override to pr-259-route
Waiting (up to --wait-timeout=3m0s) for sandbox to be ready...
✓ Sandbox status: Ready: All desired workloads are available.
✓ Local destination localhost:8083 will override sandbox responses as follows:

All HTTP/gRPC requests intended for sandbox pr-259-route, workload route, port 8083 will be sent to your local service at localhost:8083.

* If your local service (localhost:8083) responds with header `sd-override: true`:
    -> Response from your local service (localhost:8083) is returned to the client.
* Otherwise:
    -> Request is forwarded to the sandbox (pr-259-route).
