Remove default_from_api from liveness_probe field in Cloud Run v2 service

[yanweiguo]

Fix hashicorp/terraform-provider-google#17468.

Cloud Run doesn't set a default value for liveness probe. Marking liveness_probe field with default_from_api: true was a mistake.

Release Note Template for Downstream PRs (will be copied)

cloudrunv2: `liveness_probe` field in `google_cloud_run_v2_service` resource no longer has a default value from API side. Removing this field and applying the change will remove liveness probe from the Cloud Run service.
