update Art Installation README w/new aircrack info

[nbriz]

at the moment i don't think we're mentioning anywhere on this doc specifically that aircrack is a dependency, +we should also specify that it requires version download.aircrack-ng.org/aircrack-ng-1.2-beta3.tar.gz

Interesting that it requires beta version. Was there some new bugfix or feature that this project depends on?

I had good luck getting things working (as far as I could tell once I made some minor changes) with stock package on Ubuntu 18.04 LTS:

$ apt-cache show aircrack-ng

Description-en: wireless WEP/WPA cracking utilities
 aircrack-ng is an 802.11a/b/g WEP/WPA cracking program that can recover a
 40-bit, 104-bit, 256-bit or 512-bit WEP key once enough encrypted packets
 have been gathered. Also it can attack WPA1/2 networks with some advanced
 methods or simply by brute force.
 .
 It implements the standard FMS attack along with some optimizations,
 thus making the attack much faster compared to other WEP cracking tools.
 It can also fully use a multiprocessor system to its full power in order
 to speed up the cracking process.
 .
 aircrack-ng is a fork of aircrack, as that project has been stopped by
 the upstream maintainer.
