[Pro] Allow disabling html escape for Product Archive Not Found Message

## Prerequisites
- [x] I have searched for similar features requests in both open and closed tickets and cannot find a duplicate.
- [x] The feature is still missing in the latest stable version of Elementor ( Elementor Pro. )

**What problem is your feature request going to solve? Please describe.**
Post archives have a filter that we can include in `functions.php` to remove the HTML escape for the "nothing found message". This filter is NOT available for the nearly identical WooCommerce product archive.

**Describe the solution you'd like**
The ability to add a similar filter like ` add_filter( 'elementor_pro/theme_builder/archive/escape_nothing_found_message', '__return_false' );` to allow disabling the HTML Escaping for product archive not found messages.

**Describe alternatives you've considered**
I've tried overriding the render for the `products.php` module but was unable to get it working correctly. Modifying the plugin itself to remove the html escape works fine but is obviously not a long-term solution.
