doc: rewrite random_page_cost description
This removes some of the specifics of how the default was set, and adds
a mention of latency as a reason the value is lower than the storage
hardware might suggest. It still mentions caching.

My apologies that I used the incorrect "Discussion" URL above. It
should have been:
https://postgr.es/m/80d8b470-50fe-40df-b692-3292dd015595@vondra.me
I had two random_page_cost threads in my mailbox and unfortunately used
the older one.
