Add action to jump to the previously selected tab

[jceb]

Ghostty currently has an action to select the "previous tab", however, I have in mind tmux' last-window function. When I'm on Ghostty's tab 1 and then go to tab 5, I would like to be able to jump back and forth between tab 1 and 5 by pressing one key binding.
