fix: selectWoo not initializing on layered nav dropdown widget

[JimmyAppelt]

Summary

Fixes the layered nav dropdown widget (WC_Widget_Layered_Nav) widget not applying Select2/selectWoo enhancement when using OR

Since #40686 (WooCommerce 8.3.0), frontend scripts are registered with array( 'strategy' => 'defer' ) by default. The dropdown widget inline scripts register their handles with only jquery as a dependency:

wp_register_script( $handle, '', array( 'jquery' ), WC_VERSION, array( 'in_footer' => true ) );

In https://github.com/woocommerce/woocommerce/blob/trunk/plugins/woocommerce/includes/widgets/class-wc-widget-product-categories.php#L244 this is already added.

Taking into consideration the very minimal change in the code base (literally just this dependency: https://github.com/woocommerce/woocommerce/pull/63275/changes#diff-9ef3168fc51f8172e2e2df63d7b86fcf7d02461406e25728e5930610bda8030dR300), would it be possible to change the milestone to 10.6.0?
