Update firewall-sftp.md

I am an Azure networking support.  I noticed this document includes a route table configuration pointing to the Azure Firewall public IP, which is not required. Could you remove this configuration from the document?

# Create the route table
$routeTableDG = New-AzRouteTable `
  -Name Firewall-rt-table `
  -ResourceGroupName "$rg" `
  -location $location `
  -DisableBgpRoutePropagation

# Add the default route
Add-AzRouteConfig `
  -Name "DG-Route" `
  -RouteTable $routeTableDG `
  -AddressPrefix 0.0.0.0/0 `
  -NextHopType "VirtualAppliance" `
  -NextHopIpAddress $pip.ipaddress `
 | Set-AzRouteTable
