replacing-udev: update with instructions for libudev-zero

[git-bruh]

Just needed a few minor modifications, not sure if we should still keep the static xorg configuration since its a PITA to get working (in my experience).

Interesting point on the Xorg configs - I had it working almost immediately (once I fixed a single typo). What was your experience, exactly? I think my experience is outside the norm for... basically every Xorg user, tbh, so I'm curious!

We should note that the mdev service provided by busybox actually blanks out /proc/sys/kernel/hotplug and conflicts with using the helper, no? @illiliti

I don't really remember anything about the static xorg config, it was a couple of months back :p, so dunno if I didn't bother much with it or just never got it working, so my initial comment is sort of misleading. As for mdev and the helper, the helper method is marked with (Alternate method) below the mdev method.

Ah! Of course. I miss the part that says 'alternative'.

It seems fine. Static Xorg configuration could potentially be a separate article (it is, after all, very KISS to eschew device managers), but I am fine with removing it.

I'll merge this and disambiguate the install guide.
