fix: add the LOG_STREAM_RUN_GCLOUD_NOT_FOUND code in the proto file

[renzodavid9]

Related : #8012

Description
In #8012 we added a new error code directly to the skaffold.pb.go and nums.pb.go files, without updating the enums.proto file; skaffold.pb.go and nums.pb.go are autogenerated when running ./hack/generate-proto.sh, so, without the changes in the enums.proto the go files are out of sync.

This PR adds the code to the enums.proto file, and commits the result from running ./hack/generate-proto.sh. The error name had change too.
