Finally got gnome-terminal to run on my system

Apparently it needed some kind of GTK desktop portal or the other
🙄

Interesting that its numbers are basically the same as alacritty's. Lot
better than I remember, I guess the recent libvte performance work was
good.

By default, the benchmark kitten suppresses actual rendering, to better
focus on parser speed, you can pass it the ``--render`` flag to not suppress
rendering. However, modern terminals typically render asynchronously,
therefore the numbers are not really useful for comparison. However, even
with rendering enabled kitty is still much faster than all the rest. For
brevity those numbers are not included.
therefore the numbers are not really useful for comparison, as it is just a
game about how much input to *batch* before rendering the next frame.

gnome-terminal is left out as I could not get it to start on my system and
foot is left out as it does not run under X11. Alacritty+tmux is included
just to show the effect of putting a terminal multiplexer into the mix
(halving throughput) and because alacritty isnt really comparable to any of
the other terminals feature wise without tmux.
