Improve clarity of proxy mode access instruction in 'Using Source IP' tutorial

[888iee]

This is a Feature Request

What would you like to be added
After Line 95 of source-ip.md, add kubectl port-forward -n kube-system kube-proxy-88gnk 10249:10249`.

Why is this needed
In Line 95 of source-ip.md, it says Get the proxy mode on one of the nodes (kube-proxy listens on port 10249):, following with a curl command to execute. I started kubectl proxy but wasn"t able to curl http://localhost:10249/proxyMode. First I had to execute kubectl port-forward -n kube-system kube-proxy-88gnk 10249:10249

Comments
After troubleshooting, I understand that the line Get the proxy mode on one of the nodes (kube-proxy listens on port 10249): could also mean to do what I wrote, but I didn't understand initially.
