Walkthrough

The pull request removes the developer_name input variable from the Pub/Sub Terraform module configuration. The variable declaration is deleted from terraform/modules/pubsub/variables.tf and its corresponding argument reference is removed from the module instantiation in terraform/main.tf. All other module configurations and variables remain unchanged.
