Subject: [PATCH] Enable GRPC log for GNMI (#20798)

#### Why I did it
Currently, we don't have GRPC logs for the GNMI server, making it difficult to debug GRPC-level issues such as invalid certificates.

#### How I did it
Update gnmi-native.sh to enable GRPC_GO_LOG.

#### How to verify it
Send gnmi request and check gnmi log, for example:
2024 Nov 13 07:35:03.454423 str3 INFO gnmi#supervisord: gnmi-native WARNING: 2024/11/13 07:35:03 [core] grpc: Server.Serve failed to complete security handshake from "127.0.0.1:43530": tls: failed to verify client certificate: x509: certificate signed by unknown authority
