Need to set class schema for check_schema and create_schema tasks

The class awareness was added in https://github.com/astronomer/ask-astro/commit/c45487c7f12a9424dbe885580c687e35e30b7de4 but the json schema file still references "Docs".

The check_schema and create_schema tasks will need some logic to update the class name.
