## What this PR does / why we need it:
In https://github.com/kubernetes/ingress-nginx/issues/5651 there was a
request to throw an error when there are two ingresses defining the same
host and path, which was implemented as part of the validation webhook.
Despite of this there are clear rules on the ingress controller that
describes what the controller would do in [such situation (the oldest
rule wins)](https://github.com/kubernetes/ingress-nginx/blob/main/docs/how-it-works.md?plain=1#L27)
Some users are relying on this validation behaviour to prevent
misconfigurations, but there are use cases where allowing it, maybe
temporarily, is helpful. Those use cases includes:
- Splitting large ingresses objects in smaller ones https://github.com/kubernetes/ingress-nginx/issues/10820
- Moving ingress objects between namespaces without downtime (like when you transfer an ingress from team A that owns namespace A to team B that owns namespace B) https://github.com/kubernetes/ingress-nginx/issues/10090

* docs: Clarify from-to-www redirect direction.
This was not clear to me when reading the docs whether the ingress will
redirect from non-www to with-www or the reverse. It's also not very
clear from just grepping around the codebase. I found the answer by
reading from this reddit link:
https://www.reddit.com/r/kubernetes/comments/pbl033/k8s_ingress_redirecting_www_to_nonwww_domains/
So, to save time for other people doing the same, which I assumes is a
lot of people since it's a common scenario, this little revision in the
docs is warranted.
