Title: Fix chained resource example using both left and right arrows

In the resource chain:

File['/etc/ntp.conf'] -> Service['ntpd'] <- Package['ntp']

the file and package were described as related to each other, but
that indirect relationship through theh service is not meaningful here.
Stating that they are not directly related to each other makes it
clear why the file may be managed before the package.
