[docs] Add lpeers output to ntp monitoring The ntp monitoring had an example of opeers output and had a tip explaining some versions have lpeers and some others opeers. These two are in fact two separate, although similar commands, and as far as I know both of them are available in all modern versions. Added an lpeers output, but had to change the lpeers output as well to keep things consistent. I also changed the tip to reflect this.
