Workflow attributes - Unable to set null as a default value for a boolean

[barillet]

Summary
I want to create create a boolean workflow attribute with a null default value, but it is converted to false automatically

Steps to reproduce
Add something like that in the appropriate workflow :

workflows:
    <workflow_name>:
        attributes:
            boolean_att:
                property_path: <path>
                type: boolean
                default: null

Actual Result
In the database, the column boolean_att is set to false.

Expected Result
The boolean_att have to be set to null by default to have a rendered unchecked radio buttons.

Details about your environment

• OroPlatform version: 6.1.6
• PHP version: 8.4.11
• Database (MySQL, PostgreSQL) version
  Additional information
  I have managed to set it to a nullable attributes by updating the condition in WorkflowConfiguration.php#L271-L273 to the following :

if (!empty($value['type']) && in_array($value['type'], $castedTypes, true) && (!array_key_exists('default', $value) || !is_null($value['default']))) {
    settype($value['default'], $value['type']);
}

I've done a patch for it in our project by I just want to ask if this is the suitable approach. If yes, maybe this should help for the next release.
