Alpine: SSH access for non-root users will require openssh-server-pam

[abbott]

SSH access did not work for the non-root user created by my hardening script. I usually harden Debian, which is why this issue did not surface until using Helper Scripts default configuration for Alpine.

In my case, openssh-server-pam had to be installed and with UsePAM yes

Suggested paths to prevent end-users from wasting time:

• Provide an FYI/note about PAM in the Helper-Scripts.com documentation for Alpine instances
• Provide an APK option during install (Advanced path atleast) to select either openssh or openssh-server-pam
• Replace openssh with openssh-server-pam (1,000 byte install size increase)
