annotation permanent-redirect do not support '%20'

Hello Y'all,

We were migrating from on-prem K8s to AKS. As we started to use "Managed NGINX ingress with the application routing add-on" we ran in to some issues with annotation validation.

For example:
if I set permanent-redirect value to something that contains '%20' I receive and error - validators.go:237] validation error on ingress prod-ns/redirect-org: annotation permanent-redirect contains invalid value https://super-site.sharepoint.com/sites/teams/IT/devops123/IT%20OPS

This is real example:
```
nginx.ingress.kubernetes.io/permanent-redirect: https://super-site.sharepoint.com/sites/teams/IT/devops123/IT%20OPS
```

Questions:
1. Is there a way to make it work?
2. If not, can annotation validation be disabled for Managed Nginx ingress?

P.S. I have used this article to setup Nginx ingress class and ingress controller - https://learn.microsoft.com/en-us/azure/aks/app-routing-nginx-configuration
P.S.S. Old version of nginx installed from Helm works fine.

Start at validators.go:237 and reproduce validation using the permanent-redirect annotation value shown in the issue. Trace how encoded spaces are checked in the Managed NGINX ingress path and compare the behavior with the Helm-installed controller. Done means the supported behavior or a documented configuration path for this annotation is established.
