[arch-general] note about beginners guide

In installation chapter we can see:

Available time zones and subzones can be found in the |/usr/share/zoneinfo/<Zone>/<SubZone>| directories.

it's helpful to see the available time zones. To do so, cd to the directory:

# cd /usr/share/zoneinfo/

then type:

# ls

Why not type just this ? ls /usr/share/zoneinfo/ One string is better than five, and more more obvious, I think. Then...

To list down the contents of that directory. You can do the same to get subzones:

# cd /usr/share/zoneinfo/Europe # ls

And why not type just ? ls /usr/share/zoneinfo/Europe
