Q: I am encountering the error "protoc-gen-go-grpc: program not found or is not executable" while using protoc to generate GRPC output files.

1. Install the Plugin: The missing plugin is provided by the google.golang.org/grpc package. To install it, run the following command:

   go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

2. Verify Installation: Once the plugin is installed, check if it's available in your system's $PATH. You can do this by running:
