Implement a new step type that allows users to define groups that are scoped to the definition rather than using pre-defined Jira groups.
The step should include a select field, allowing users to pick and group users dynamically in real-time.

Ensure that the step works as follows:

• Users can create custom groups without relying on Jira’s pre-defined groups

• A select field is presented for user selection, enabling on-the-go group creation

• The created group should be available within the scope of the current definition

Accepted criteria

• A new step type is available for defining groups scoped to the definition

• Users can select individuals dynamically and group them during the configuration

• Groups defined in this step are available only within the current definition scope
