Starting from nginx ingress controller Version 0.22.0 onwards, it uses placeholders /$1 or /$2 soon for rewrite-target annotation (#15504)

In nginx ingress controller Version 0.22.0 and beyond, any substrings within the request URI that need to be passed to the rewritten path must explicitly be defined in a capture group. Please refer doc here : 
* `https://kubernetes.github.io/ingress-nginx/examples/rewrite/#rewrite-target`
* `https://stackoverflow.com/a/55193468/5527839 `

Currently, what was mentioned in the docs, didnt work for me. I was using minikube version `1.2.0` which uses ingress above v0.21.0. After reading the docs provided in above two links, was able to figure out where it was lacking. Have mentioned the changes in the proposed file change.
