Moose create aggregation or boilerplate aggregation

[linear[bot]]

As a developer, I should be able to create a new template file for a new aggregation through the moose cli.

When the developer runs the following command in the moose CLI: moose aggregation init :

• Moose generates a new file in the /aggregations folder named: .ts
• The contents of the newly generated file matches the contents in the snippet https://www.figma.com/file/Eyi7IU5j9uYQAXD8H79UhI/Aggregations-and-Consumption?type=whiteboard&node-id=265-2965&t=QatIK1YNF6cybBbC-4
