Adding SSL Support for ENV

[SirLouen]

I think to have the full testing suite that its needed to add easy SSL support

One idea that comes to my mind is, leaving everything set up, and create a npm command to generate the SSL certs in our desired folder, or ship this with self-signed certificates. Either of the two options could work, obviously the second one is easier to implement.

I'm going to create a very simple patch just to showcase this idea, but it needs further work.

Following the idea, this just introduces the self-signed certificates and some little tweaks in both nginx and docker-composer.yml

More work is required to make a polished result of a potential implementation of SSL for the testing environment, very useful to test some patches and reports that require SSL for testing.

Testing a thing

Second part of this testing.

I've closed #63172, #63135 because with Docker override it's possible to have them onboard. But this is not totally possible.

I would like to think about how this could be achieved. There are a lot of tickets that need HTTPS testing and its so easy to add this to the docker environment.

cc @westonruter to see if you can give me some ideas on how to improve this.

@SirLouen Sorry, I don't have any special insights to implement this.
