Remove radio button checked value in mail delivery option

Currently the delivery via mail is set as checked by default and the other mode remains at the bottom of the page so the customer discovers that the other option exists only after filling in the data in the first form and it is very annoying. I have noticed that many have to rewrite everything and many drop out at that point looking at the hotjar recordings.

I solved it by removing the value checked=’checked’ in row 126 and 134 in file woo-vou-recipient-fields.php but you will surely find a definitive solution.
