Added Mirrored networking mode detail for WSL

Fix: #844

This is not necessary, and further, this mirrored networking mode works only on Windows 11.

Here is how we make WSL clients work with a Garnet Windows server in general:

• Start GarnetServer in Windows, listening to 0.0.0.0 (IPAddress.Any). Use the argument --bind 0.0.0.0 if necessary.
• Add GarnetServer.exe to firewall exceptions (Windows Defender Firewall -> Allowed apps)
• On WSL, get the host IP address using ip route show | grep -i default | awk '{ print $3}'
• Connect from WSL using redis-cli -h <address>

You could edit the docs to offer this alternative first. And mention the mirrored mode only for Windows 11, and only if the above did not work for some reason.
