The make lint target is complaining about local changes

### Description

```
Please run 'make generate' when making changes to proto files and check-in the generated file changes
make: *** [Makefile:504: check-generated] Error 1
```

It should only do this for *.pb.go, and not for *.go

I want to be able to run golangci-lint, before I commit

Running "make generate" doesn't change anything.
