CH04::privkeys: drop note about human-generated randomness

Browse Source 
This was probaby the case on some JS-based private key websites, or when
using something like GPG, but it's unlikely to be the case on any modern
production software.

@ -138,11 +138,8 @@ The first and most important step in generating keys is to find a secure
source of entropy, or randomness. Creating a bitcoin key is essentially
the same as "Pick a number between 1 and 2^256^." The exact method you
use to pick that number does not matter as long as it is not predictable
or repeatable. Bitcoin software uses the underlying operating system's
random number generators to produce 256 bits of entropy (randomness).
Usually, the OS random number generator is initialized by a human source
of randomness, which is why you may be asked to wiggle your mouse around
for a few seconds.
or repeatable. Bitcoin software uses cryptographically-secure random
number generators to produce 256 bits of entropy (randomness).
More precisely, the private key can be any number between +0+ and +n -
1+ inclusive, where n is a constant (n = 1.1578 * 10^77^, slightly less
