Correct the documentation for OPENSSL_sk_find

Since April of 2023 with commit eb0935f, these functions have not
sorted the stack if it was not sorted. The documentation was noti
changed at the time to reflect this changed behaviour.

This corrects the documentation to reflect the current behaviour
of these functions

 B<sk_I<TYPE>_find_ex>() operates like B<sk_I<TYPE>_find>() except when a
 comparison function has been specified and no matching element is found.
