Added support for arch and manjaro with pacman

[TalenMud]

added another elif statement into the script so if arch or manjaro are found it uses pacman.
I also added another elif statement to the sudo installation line using pacman.

Thanks for the pull request! I know this is probably unnecessary to ask, but did you test it on your system first? (I don't have a computer running Arch right now)

(Closes #2)

Also, could you also add EndeavourOS too?

By the way, is there any difference between this and the dependencies listed on the Aseprite official guide?

[TalenMud]

I'll test it out as soon as I can and let you know how it works on arch, sorry I should've tested properly before sending the pull request.

Tried running it on manjaro, it gave me this error:

It fails with the following output:

any ideas?

Did you install git? I don't think the script automatically installs that (except for apt distros?). I should probably add that if it starts working after you do that.

Also did you try
sudo pacman -S gcc clang libc++ cmake ninja libx11 libxcursor mesa-libgl fontconfig libwebp before you ran the script? Those were the official dependencies from aseprite's build guide.
