Modify sshd_config to match Linux when enabling OpenSSH Server

[RuiNtD]

Is your feature request related to a problem? Please describe

Windows adds the following lines to sshd_config:

Match Group administrators
       AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys

These lines make it so admins have to put their SSH keys in %ProgramData%\ssh\administrators_authorized_keys and causes %UserProfile%\.ssh\authorized_keys to be completely ignored. This is intentional behavior according to Microsoft docs, but it causes a lot of confusion and frustration since it's inconsistent with OpenSSH Server on Linux.

Describe the solution you'd like

When the user uses the "Enable OpenSSH Server" button, WU should remove or comment out the lines above at the end of sshd_config.

Describe alternatives you've considered

Update the output in WU's console when enabling OpenSSH Server to mention this behavior. Currently, it just says:

Add your public keys to this file -> C:\\Users\USERNAME\.ssh\authorized_keys

Which doesn't even work for admins.
