Fix TypeError in webhook job templates with shopify_api >= 16.0.0

   Unblock users experiencing TypeError when registering webhook handlers due to Sorbet type checking introduced in shopify_api-16.0.0

   Changed  to  for ShopifyAPI::Webhooks::WebhookHandler in all webhook job templates. This makes the class object itself satisfy the WebhookHandler type expected by
   WebhooksManager.add_registrations

   Affected templates:
   - app_uninstalled_job.rb.tt
   - customers_data_request_job.rb.tt
   - customers_redact_job.rb.tt
   - shop_redact_job.rb.tt
   - webhook_job.rb.tt
