Kitty supports ligatures and seems to have better font rendering. It's
memory consumption seems to be high however, it should allow us to
replace tmux or we can still use tmux with it if required while relying
on the window layouts and tabs feature to prevent us from requiring
spawning any more terminals. Spawning one kitty instance would be
sufficient to take care of everything.
While st is awesome, supports ligatures and consume just around 10MB of
memory running it requires having to run Xwayland. For now, switch to
alacritty so we need not run Xwayland or any X clients.
If we find a better terminal later on we can switch to that.
