chore: update libcosmic

keyboard input has changed a lot in iced, but I think I've made the proper adjustments here. vertical splits don't seem to work, but that didn't seem to work before either. Also, there is a black border on the right and bottom of the first tab of the terminal. I'm not sure why yet, but it seems like it is probably related to the scrollbar
