website: stale link to parts library

[KJ7LNW]

Describe the bug

The link on the website is no longer valid:
https://www.leocad.org/docs/library.html points at http://www.ldraw.org/library/unofficial/ldrawunf.zip which is a 404.

The new link is https://library.ldraw.org/updates?latest or maybe https://library.ldraw.org/library/updates/complete.zip

Also, the documentation says this:

 $ set LEOCAD_LIB=C:\User\Downloads\complete.zip 

which doesn't work, but first extract the zip and then it does:

$ set LEOCAD_LIB=C:\User\Downloads\ldraw

Actually in Linux I did this, but kept the Windows example above:

# Doesn't work:
LEOCAD_LIB=/usr/share/leocad/ldraw/complete.zip leocad 

# *Does work* after extracting:
LEOCAD_LIB=/usr/share/leocad/ldraw/ leocad

the env var works for me

Just to confirm, does it work if you pass the .zip in the environment, without extracting the .zip first?
