Expect WSL to use the configured subnet.

### Actual Behavior

This output and the registry settings are changed:

wsl: Failed to create virtual network with address range: '192.168.235.0/20', created new network with range: '172.22.240.0/20', Element not found.

### Diagnostic Logs

Start by reproducing the issue with the provided WSL setup commands and the NatGatewayIpAddress and NatNetwork registry values, then inspect the linked WslLogs diagnostic archive. Done means WSL uses the configured subnet and gateway without falling back to a different network or reporting “Element not found”.
