Review the existing Cloud Run module at modules/cloud_run and the Terraform Google provider documentation for the cloud_run_v2_service resource. Understand the differences between the v1 and v2 APIs. The work involves creating a new module, likely in a new directory, that replicates the functionality using the v2 resource. Check for any existing tests or examples to follow.
