Table with Bulk Edit Modal v4

We add a new Bulk Action where adding a schema() opens a modal with a form.

app/Filament/Resources/Posts/Tables/PostsTable.php:

BulkAction::make('Change author')
    ->icon(Heroicon::OutlinedPencilSquare)
    ->schema([

            ->label('Author')
            ->relationship('author', 'name')
            // ...
