Installation guide

I think the installation guide should be updated since the package is now included in the official repos of some distros so now it's possible to install it via directly pacman for or snap for example. So these installation methods should now be included in the guide

We have no involvement in these repos/distros, so we can't officially endorse their correctness, trustworthiness, up-to-date-ness, etc. Therefore, we will only reference our own official release in the document.
