HostsFile Get-TargetResource returns an array for HostName if there is one or more spaces at the beginning of the line

Problem description

HostsFile Get-TargetResource returns an array for HostName if there is one or more spaces at the beginning of the line. This formatting appears to come from the PowerToys Hosts File Editor.

Start at the HostsFile Get-TargetResource entry point and reproduce the issue with Invoke-DscResource using a hosts line with leading spaces. Ensure the returned HostName is a scalar hostname rather than an array containing the IP address, while preserving normal hosts-file parsing.
