Update size check condition for probable primes to align with FIPS 186-5.

Update size check condition for probable primes to align with FIPS 186-5.

Fixes #28540

In FIPS 186-4 (Table B.1), the upper bounds for probable primes p and q were
defined using strict inequalities. In FIPS 186-5, Table A.1 replaces the
previous Table B.1 (dropping the nlen=1024 case) and revises the upper bound
condition to use weak inequalities.
