doc/rados: add blaum_roth coding guidance

Direct Ceph administrators using blaum_roth coding for erasure-coded
pools to change the default value of w=7 to a different value in order
to ensure that w+1 is prime.

This information was provided to the Ceph upstream by Benjamin Mare in
September of 2024.
