rewrite-target, rewrite-target lint

Is this a BUG REPORT or FEATURE REQUEST? (choose one):

NGINX Ingress controller version: 0.24.1

Kubernetes version (use kubectl version): v1.13.7-gke.8

Environment:

• Cloud provider or hardware configuration: GKE
• OS (e.g. from /etc/os-release): Ubuntu

What happened:

When running kubectl ingress-nginx lint --verbose --all-namespaces and using the exact same samples from here (change from here), the following error happens:

✗ ns/ingress-name
  - The rewrite-target annotation value does not reference a capture group
      Lint added for version 0.22.0
      https://github.com/kubernetes/ingress-nginx/issues/3174

It seems that the linter only checks for the occurence of "$1" within the rewrite-target annotation, not "$2" (or anything else thats also supported). See here.

What you expected to happen:

No lint error.

How to reproduce it (as minimally and precisely as possible):

Use the rewrite-target sample from here und run the linter command (kubectl ingress-nginx lint --verbose --all-namespaces).
