WooCommerce Product Bundles 8.4.0

* Dev - Added 'woocommerce_after_bundle_price', 'woocommerce_before_bundle_availability', and 'woocommerce_before_bundle_add_to_cart_button' hooks.
* Tweak - Increased the discounted price precision relative to the store precision to prevent errors such as: $10 x 10 = $100 before discount, and ( $9.5 rounded to $10 ) x 10 = $100 after 5% discount.
* Fix - Bundled item totals are now rounded before calculating the Bundle total, to prevent inconsistencies between the total calculated via JS and the catalog price of a Bundle.
* Fix - Fixed 'Too few arguments to function WC_PB_Order::get_product_from_item' error when reading order data via the REST API.

* Fix - Fixed PHP 8 'Required parameter $cart_item_data follows optional parameter $quantity' warning.
* Fix - 'Add' checkbox not working for Variable bundled items when configuring Product Bundles in editable orders.
* Fix - Fixed a rare infinite loop affecting bundle-sells when using Memberships, Subscriptions, All Products For Subscriptions, and Product Bundles.
* Tweak - Reduce movement on the screen by keeping the 'Clear' variation attributes link visible at all times.

* Fix - PHP warning on activation due to use of deprecated function 'WC_Admin_Note::set_note'.
* Tweak - Append plugin version number to @font-face file names for improved compatibility with CDN plugins.
* Tweak - Prevent 'Free!' string from appearing on page load when 'Name Your Price' is enabled on Product Bundle containers.
