Build without deployment

There's a use case where a dacpac might be needed to save to pipeline artifacts or do other deployments - can the action be provided a sqlproj file without connection info to output a dacpac in the pipeline?

The issue names no files or tests. Start by tracing the action's SQL project build entry point and workflow inputs, then determine how a sqlproj and dacpac are handled without connection information; done means the requested pipeline artifact workflow is supported and verified.
