Add public $translatable = ['*'] as wildcard.

October has an amazing behavior \System\Behaviors\SettingsModel::class, which is made a simple custom business logic setup.
After 2 months of development, we noticed that the number of fields in the model exceeded 50.
And when adding a new field, we have to constantly update the model itself and add the name of this field to the translatable array. Of course, the human factor leads to bugs.
We suggest to add asterisk support as wildcard for all existing fields as it works in other service arrays:
protected $guarded = ['*'];
but this time:
public $translatable = ['*']

It is a nice idea and should be simple to implement, although the results may be unpredictable since a block-list would be required for some core attributes. For example, NestedTree has nest_left, nest_right, etc. It may be difficult to predict all the possibilities.
