change chain-command within readme

[CodingWithAnxiety]

I propose we change the chain-command within the readme from;

pacman -S --needed git base-devel && git clone https://aur.archlinux.org/yay.git && cd yay && makepkg -si

to

sudo pacman -S --needed git base-devel && git clone https://aur.archlinux.org/yay.git && cd yay && makepkg -si

The only command in this that needs sudo is pacman- and running the full command as root does not work;

==> ERROR: Running makepkg as root is not allowed as it can cause permanent,
catastrophic damage to your system.

This new commands satisfies the usage of sudo (pacman needs root) without overusing it and receiving an error from makepkg.

can you add a small mention saying to replace "sudo" with your privilege escalation tool of choice?

Thanks @CodingWithAnxiety
