CentMin & nginx 1.25.1 mainline upgrade

[TPerry]

I know there are several CentMin Mod users present here... just a little warning. If you are using mainline version of nginx and you decide to upgrade to 1.25.1, odds are your site(s) will be down after the upgrade.
There is a reason for that... and it's a VERY easy fix.
It's detailed over on @eva2000's CentMin Mod forum, and you REALLY need to visit there regularly if you are using his fantastic offering.
You can find what you need to do here. It has, in a nutshell, to do with the HTTP2 parameter deprecation on the listen directive for SSL setups.

Actually Nginx 1.25.1 won't break anything as yet. From https://community.centminmod.com/threads/nginx-1-25-1-release-http2-parameter-deprecation.23890/ it's only a deprecation warning message, so HTTP/2 HTTPS will still work for now but eventually 1.25.2+ or later will remove http2 parameter support in favour of http2 directive support.
