Document dependency for Linux installation

[MassiminoilTrace]

While trying to run an example Dioxus 0.5 project with the latest dx tool, targeting dioxus_desktop, I had a linking error. I got the same error both on Debian12 and Ubuntu 22.04, on different computers.

I installed all the suggested Tauri dependencies, but the error still appears. ld complains about a missing xdo library.

Installing the package libxdo-dev fixes the problem :)

For archlinux:

sudo pacman -S xdotool
