goto_split looping

[silby]

On iTerm 2, I have cmd-j and cmd-k mapped to "select split pane below" and "select split pane above", respectively. If I use cmd-j on the bottommost split in a tab, it focuses the topmost split, resp. cmd-k on the topmost split goes to the bottommost split. In ghostty, goto_split:up and goto_split:down don't loop around. I'd like to be able to replicate this iTerm2 keybind in ghostty.
