[Wiki] Simplify steps on Configure Script Addition section for one command

[manugildev]

Replace wiki/Installing-yabai-(latest-release)#configure-scripting-addition steps by just running this command on the terminal.

sudo touch /private/etc/sudoers.d/yabai && echo "$(whoami) ALL=(root) NOPASSWD: sha256:$(shasum -a 256 $(which yabai) | cut -d ' ' -f 1) $(which yabai) --load-sa" | sudo tee /private/etc/sudoers.d/yabai

These steps are very much "overcomplicated" on purpose, because I want users to be aware of what they are doing, instead of just copy-pasting some command.

I have added this information to the wiki as additional information, but I will not remove the previous part.
