Revise IPs in site2site article

For those not netowrk savvy, it may be confusing that you have different IPs in the network diagram vs the examples provided for entering network objects in https://support.sophos.com/support/s/article/KB-000036746?language=en_US. Novices will try and match up the diagram to the object screenshots and be confused (network diagram has 192.168.1.0/24 + 192.168.15.0/24 but network object example have completely diffrent ranges)
