Fix #14986 This PR includes some refactoring to simplify the interaction of the `NodeWorkflow` and the `BaseWorkflow` with the registry. We were registering redundant `addPostTransform`s. Some of them in the constructor of the `BaseWorkflow`, which did not allow us to intercept `addUndefinedDefaults`. Additionally, we were setting the `validateOptionsWithSchema` transform multiple times unnecessarily. An issue left to fix is support for the `--project` option in schematic commands. Currently, `getProjectName` does not know about this option, since `createWorkflow` does not know how to parse the command line arguments. The parsing logic is implemented partially by the concrete implementation of the `SchematicCommand` template method.
