Add redirect HTTP tp HTTPS in NGING config

[Scuruba]

Summary

Redirect HTTP to HTTPS is not activated at default and was only possible via creating a new file.
https://docs.mailcow.email/manual-guides/u_e-80_to_443/

For me, his will not work anymore after updating to 2025.1. The file will be imported, but the ports and sites will be doubled with nginx.conf.j2

Motivation

The redirect should work and also be the standard configuration.
I think the best option is to add it in the "nginx.conf.j2" file and define a config variable to deactivate it.

Additional context

I tried to change the file as described, but was not able to set the variable in mailcow.conf, so the configuration was changed.

How can I test this feature?

You can change the nginx.conf.j2 file like in my commit. But not with the variable REDIRECT_HTTP, but as if it had been answered with yes.
I try to make a commit with the other changes I made next week, but unfortunately that didn't work for me with the variables.

The config itself is working.

You should open a PR for this feature. REDIRECT_HTTP should default to yes when HTTP is enabled.
