Simple Commerce to Cargo migration: No migration for widgets

[Jamesking56]

Bug description

If you've setup some widgets with Simple Commerce, there's no migration path for them in Cargo.

Not sure if this is simply a documentation exercise or whether a new command is needed that fixes the widgets.

How to reproduce

1. Create a Statamic 5 site with Simple Commerce installed
2. Setup Simple Commerce widgets in config/statamic/cp.php as follows:

'widgets' => [
      [
          'type' => 'orders_chart',
          'width' => 100,
      ],
      [
          'type' => 'recent_orders',
          'width' => 50,
          'limit' => 5,
      ],
      [
          'type' => 'top_customers',
          'width' => 50,
          'limit' => 5,
      ],
],

3. Upgrade to Statamic 6
4. Install Cargo and run the migration steps
5. Login to the CP to find that it now errors due to the widgets no longer functioning

Cargo doesn't currently have any widgets, so there's nothing for it to migrate to. I'm planning to add some soon though, with a migrator.
