docs: deprecation: OOM-score adjust for the daemon 

The `oom-score-adjust` option was added to prevent the daemon from being
OOM-killed before other processes. This option was mostly added as a
convenience, as running the daemon as a systemd unit was not yet common.

Having the daemon set its own limits is not best-practice, and something
better handled by the process-manager starting the daemon.

Docker v20.10 and newer no longer adjust the daemon's OOM score by default,
instead setting the OOM-score to the systemd unit (OOMScoreAdjust) that's
shipped with the packages.

Users currently depending on this feature are recommended to adjust the
daemon's OOM score using systemd or through other means, when starting
the daemon.
