Add Ice Ice Bergy theme

[jmsdnns]

Similar to Iceberg, but I find it's easier on the eyes. Screenshots available here: https://github.com/jmsdnns/zed-iceicebergy.

Hmm. From what I can tell, the check didn't fail because of my theme. The log output suggests it is something to do with a package called kanagawa-themes.

To simplify things, the error says to use extension.toml. The one in my theme is right here: https://github.com/jmsdnns/zed-iceicebergy/blob/main/extension.toml

Your branch needed to be updated with the latest changes from main.
