Add `apple-touch-icon` support for better Safari bookmarks

[Anisubhra]

Hi 👋

First of all, thank you for building and maintaining JSFiddle. It’s an incredibly useful tool and many developers rely on it daily.

I wanted to suggest adding support for an apple-touch-icon to the site. Currently, when bookmarking JSFiddle as Favorites in Safari, it shows the default letter-based icon with an accent background instead of a proper site icon.

Adding an apple-touch-icon would allow Safari bookmarks and home screen shortcuts to display a proper icon, which would improve the visual experience and make the bookmark look more polished.

Example:

<link rel="apple-touch-icon" href="/apple-touch-icon.png">

Since many developers use JSFiddle across Apple devices, this small addition could make bookmarking the site feel more consistent with modern web practices.

Thanks again for the great work! 🙌
