Documentation: Enums embedded in Class

Suggestion to clarify documentation:

Please note:
When using Enums defined inside a Class they have to be specified on the property including the Class name

class EnumEntity: Entity {

    enum TestEnum: Int {
        case unknown = 0
        case first = 100
        case second = 200
        case third = 300
    }

    var id: Id = 0
    // objectbox: convert = { "default": ".unknown" }
    var custom: EnumEntity.TestEnum
}

Start by locating the documentation section covering enums and the convert default syntax. Use the EnumEntity.TestEnum example from the issue to clarify the required class-qualified property type, then check nearby examples for consistent wording and formatting. Done means the documentation explicitly covers nested enums and includes a clear example.
