Fix typo in the description of RandomNumberGenerator.state

The second note of this doc mentions that "the value documented here is [...] not the actual default seed". I have corrected this to say that it's not the default "state" instead, since it has no reason to ever match the seed.

It should only be set to values that came from the state property itself. To initialize the random number generator with arbitrary input, use [member seed] instead.
