Workflow transition
• The From state field needs to be updated.
• The To state field needs to be updated.

Steps to reproduce

- install Workflow 8.x-1.0
- update to Workflow 8.x-1.8 or higher (or lower)
- check the report

Proposed resolution

This is because changes/improvements are done on the Workflow Fields.
However, changes schema/field definitions are not (completely) supported by Drupal core.

See for example core issue 🐛 Stale field settings used by options_allowed_values prevents widgets from updating the allowed values. Needs work

Remaining tasks

- update the schema/field definition.
- See function WorkflowTransition::baseFieldDefinitions();
- See function WorkflowItem::propertyDefinitions() and the settingsForm;
