Removed overkill calls to Select-Object -ExpandProperty (#412)

The script uses the . operator to access properties ($Secret.StartDateTime) except here:

$RemainingDaysCount = $EndDate - $Now |
            Select-Object -ExpandProperty Days

It is simpler to write
$RemainingDaysCount = ($EndDate - $Now).Days
