Error parsing go.mod module declares its path as: github.com/google/gnostic but was required as: github.com/googleapis/gnostic

Hi,
the recent change of the module name (from `googleapis` to `google`) causes the `go get -u ./...` command to fail in our project where `gnostic` is listed as an indirect dependency.

```
go get: github.com/googleapis/gnostic@v0.5.6: parsing go.mod:
module declares its path as: github.com/google/gnostic
but was required as: github.com/googleapis/gnostic
```

https://github.com/google/gnostic/pull/259

Manually changing the name and version in the mod file doesn't help.

Is there a recommended smooth update path?
