Cloud Run deployment may not be able to access secrets

[ag-adampike]

This step is expected to fail if the project for the deployment is not named op-scim-bridge.

scim-examples/beta/google-cloud-run/README.md

Lines 82 to 90 in 1cf870e

	5. Enable Cloud Run to access the secret using the Compute Engine default service account for the project:
	```sh
	gcloud secrets add-iam-policy-binding scimsession --member=serviceAccount:$(
	gcloud iam service-accounts list --filter="$(
	gcloud projects describe op-scim-bridge --format="value(projectNumber)"
	)-compute@developer.gserviceaccount.com" --format="value(email)"
	) --role=roles/secretmanager.secretAccessor
	```

A known workaround is to replace op-scim-bridge with the project ID in this line when running the chained command in the code block:

scim-examples/beta/google-cloud-run/README.md

Line 87 in 1cf870e

gcloud projects describe op-scim-bridge --format="value(projectNumber)"
