PW WooCommerce Gift Cards Pro 3.1

- Improvements to the French translation. Fixed a possible display issue when using a background image on the gift card email.

- Confirmed compatibility with upcoming WooCommerce v6.3

- Added a Dropdown Menu Order property to the gift card designs so that you can optionally change the sort for the email design dropdown menu. When creating a new design in the Email Designer, copy the currently selected design as a starting point. Removed several jQuery warnings for deprecated function calls. Refreshed translations to add any missing strings. WordPress 5.9 and WooCommerce 6.2 compatibility.
