Docs: how to avoid reading /var/log/btmp on each SSH login without causing security concerns for non-git traffic

https://gitlab.com/gitlab-org/gitlab/-/issues/350463#note_818555339 found that each SSH login read `/var/log/btmp` when `UsePAM` is enabled in `sshd_config` which when large can spike the CPU load. https://gitlab.com/gitlab-org/gitlab/-/merge_requests/78955 introduces troubleshooting details. How can this issue be solved for systems that need `UsePAM` enabled?
