Give vendors permissions to edit media

functions.php

<?php

// HOWEVER this requires post editing permissions so would also allow them to edit ALL posts and comments on
// your site if they know how to do it.
// WC Vendors will not support this code and is provided for educational purposes only. 
// THIS IS DANGEROUS TO DO -- USE AT YOUR OWN RISK -- YOU HAVE BEEN WARNED!
