Subject: [PATCH] Multisite: Add filter to allow custom form attributes in new
 site creation.

This change introduces the `network_site_new_form_attributes` filter
to the site creation form (`/wp-admin/network/site-new.php`) in WordPress Multisite.

The filter allows developers to modify form attributes such as `enctype="multipart/form-data"`, enabling file uploads or other custom behaviors when creating a new site.

This enhancement provides more flexibility for developers extending the multisite functionality without requiring modifications to core files.

Fixes #62086
