Safari pinned tab icon

It is probably a super easy update but I’d like to see a pinned tab icon in Safari in the next update. When I am at work, I pin the Home Assistant page and it would be nice if it had an icon.

If you add this, keep in mind that Safari aggressively caches these icons, so you may not see the change until you flush the icon cache.
