Add alt text attributes to the payment method icons in Square Online footer

[taylorandjones]

The ability to add alt text to payment icon images, or have the alt text attribute code automatically included upon toggling this element in the footer would improve accessibility for site visitors and improve SEO page performance score. Thank you for considering this feature.

**UPDATE**I've checked the browser inspector and see that alt text has been added to each of the payment icons in the footer - Thank you!
