[DOC] flagd-proxy example invalid url

[kustoffigor]

Change in the documentation

https://github.com/open-feature/flagd/tree/main/flagd-proxy here is line

• '[{"uri":"grpc://flagd-proxy-svc.flagd-proxy.svc.cluster.local:8015","provider":"grpc","selector":"core.openfeature.dev/NAMESPACE/NAME"}]'

The problem is that it works without grpc:// in the url and doesn't work with grpc://. Just tested it,
