Update icon asset on joinmastodon.org

[bertob]

Describe the request

The Tuba icon on this page is not the latest version, it'd be nice to update it :)

Implementation Details

• [X] This follows the GNOME HIG.

Hmm, this still looks a bit odd, since the website doesn't add a shadow like Flathub/Software do :/

Perhaps we could just give them an asset like this with a baked-in shadow?

I don't really see much of a difference at that size and it does make it smaller than the rest of the icons but I can push it if you confirm! (FWIW as far as I am aware they are planning to redesign the apps page, I'll probably suggest adding css shadows like flathub when the time comes)

Current:

With shadow:

Hmm, how about a stronger shadow:

New icon:

Original icon + same drop shadow as flathub:

I can PR the flathub-like shadow and see how they take it but I'm okay with PRing the baked-in shadow icon too

[bertob]

Ah interesting, I hadn't considered just adding a CSS shadow to all of them on the website, but that might make sense, yeah. I'd maybe make it a tiny bit stronger/more opaque than you have above though, since it's a smaller size than we usually use.

But yeah, I'd be in favor of trying to propose a CSS shadow and if it doesn't work we go with the baked-in one :)
