Update use of http2 listen directive to align with deprecation

[shaun-nx]

Proposed changes

As of NGINX 1.25.1, the http2 option for the listen directive has been deprecated.

This change updates our main NGINX, VirtualServer and Ingress templates to enable the new http2 directive in NGINX.

Change this:

listen 443 ssl http2;

To this:

listen 443 ssl;
http2 on;

Resolves #4237

Hi, is this PR included in v3.3.2?

I've upgraded my ingress to v3.3.2 and got the warning, I can't see the PR on the release page. So this is not released yet, right?
Please correct me if I'm wrong.
Thanks!
