From Chain Metadata

Finalize a successful crowdloan. The call will transfer the raised amount to the target address if it was provided when the crowdloan was created and dispatch the call that was provided using the creator origin. The CurrentCrowdloanId will be set to the crowdloan id being finalized so the dispatched call can access it temporarily by accessing the `CurrentCrowdloanId` storage item. The dispatch origin for this call must be _Signed_ and must be the creator of the crowdloan. Parameters: `crowdloan_id`: The id of the crowdloan to finalize.
