Content moderation state is not displaing after updating to Thunder 7

Problem/Motivation

I have updated the project to Drupal 10 and installed the Thunder admin theme as it was before. And after this update, I faced a problem that the content moderation state widget is not displaying anymore. It happens because of code from thunder_admin_form_alter was moved to \Drupal\thunder_workflow\ThunderWorkflowFormHelper::moveStateToActions

Proposed resolution

I think we can remove this unneeded code from form alter
