castor: Rebuild to install icons and desktop file
The current package in the repositories is missing all icons and the desktop file. They're present in a local build, so I'm revbumping to force a rebuild and confirm that the files are in the new package.

A patch file from https://github.com/void-linux/void-packages/pull/24806.patch is attached
