[Dev] New installation images

[Gabriele Nocentini]

Hi, I'm new to the devlist, sorry in advance for any error or grammatical mistake. A while ago I tried installing a new parabola system, I encountered issues with pacstrap: it complained about arch-keyrings. I looked into parabolaiso to build one myself, needless to say without success. I was wondering if this issue was fixable without the need of a new iso. Thanks again to all parabola devs, wish you all a great 2020
