ALL action not showing properly in the UI when creating a Repository Content Selector privilege via the REST API

[brenuart]

When creating a Repository Content Selector privilege via the REST API, it's possible to set the action as "ALL" instead of specifying each action individually. For example, you can POST the following definition to the /service/rest/v1/privileges/repository-content-selector endpoint:

{
    "contentSelector": "my-selector",
    "name": "test",
    "repository": "my-repo",
    "type": "repository-content-selector",
    "actions": [
        "ALL"
    ],
    "format": "*"
}

However, when you view the privilege details in the UI, none of the actions appear as selected, which can be confusing. Despite the misleading display, the privilege seems to function as expected, allowing the intended actions to be performed.
