Rename the parameter with an alias based on this wg-powershell-cmdlets review comment

@PowerShell/wg-powershell-cmdlets reviewed this. Based on the documentation currently, -TimeoutSec is for the initial connection and the definition of this parameter should not change. We suggest renaming this parameter to -ConnectTimeoutSec and alias to -TimeoutSec. For this new capability, we propose adding a new -NetworkTimeoutSec (default to 0 meaning infinite) to handle the case of intermittent network issues.
