Fix go-grpc generate.sh script

[huan]

To update:

1. the proto/ directory change,
2. the breaking change of the go 1.17 & code generator:
   • https://github.com/golang/protobuf/issues/1070
   • https://github.com/GoogleCloudPlatform/cloud-foundation-toolkit/issues/902
   • https://github.com/grpc-ecosystem/grpc-gateway/issues/2263

Generation is OK now.

However, it might has problems after deploy to the repo because we have introduced the 3rd parties protobuf definitions.

Need to be confirmed after the code published.

Ci seems to have no problem. The new proto has some incompatible modifications. need to modify the go–wechaty code

I have commented out the below CI code today because it keeps failing:

https://github.com/wechaty/grpc/blob/208ca779d470d796fc6ab2319a78e1e58d899be5/.github/workflows/go.yml#L37-L39

Could you please have a look at it?

Thank you very much!
