Filament: Repeater with Exactly X Items

When using Repeater, you can provide a specific strict number of items.

For example, if you want to have 3 fields to pick the winners of a tournament, you can have the ->defaultItems(X)->addable(false)->deletable(false)

Repeater::make('winners')
    ->schema([
        // ...
    ])
    ->defaultItems(3)
    ->addable(false)
    ->deletable(false);
