Subject: [PATCH] Add support for Go 1.21

Go 1.21 added a requirement for a 'go.env' file. Without that file, Go
will throw an error like:
```
Error in fail: failed to fetch org_golang_google_grpc_cmd_protoc_gen_go_grpc: fetch_repo: google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.3.0: GOPROXY list is not the empty string, but contains no entries
```

This commit adds it to the SDK exposed by rules_nixpkgs so that it is
compatible with rules_go.
