CloudRun configuration for skaffold requires `projectid` and therefore cannot be generic for deployment

The skaffold yaml file for Cloud Run requires setting of the projectid.

Currently when using solutions-builder for CloudRun configuration in the generated skaffold.yaml is hardcoded. When you make this value `your-project-id` the `sb set project-id` command would not replace the value.

```
- &cloudrun-profile # YAML anchor used by "default" profile.
name: cloudrun
manifests:
rawYaml:
- manifests/cloudrun-service.yaml
deploy:
cloudrun:
region: us-central1
projectid: your-project-id
```

Therefore you cannot have a template that everyone can deploy into their own GCP environment.

The only workaround is to use manual command instead of the `sb deploy`:

`skaffold run -p default-deploy -n default --default-repo="gcr.io/$PROJECT_ID" --cloud-run-project=$PROJECT_ID --cloud-run-location=us-central1`
