Subject: [PATCH] Revert "services: openssh: Warn about
 'password-authentication?' default."

This reverts commit aecd2a13cbd8301d0fdeafcacbf69e12cc3f6138 for two
reasons:

  1. The warning would fire every time (gnu services ssh) is loaded;

  2. There's still no clear consensus on the approach to follow as
     discussed in <https://issues.guix.gnu.org/44808>.
