Use SSL by default; add option to turn it off

[timmywil]

I'd like to use SSL as before, and it's more difficult to enable SSL than it is to disable it. I've reverted the change to use port 9412 without SSL by default, but I made it so it can easily be added back with one change:

.env

JQUERY_WP_HTTP_PORT=9412

This port is respected in the new wp-config.php, so no further changes required. I also made it so the virtual host for 443 is only created in apache if the certs are available in the SSL folder. I needed to keep 443:443 in the docker compose (conditionals are not possible and I don't want to have to construct the docker compose), but without certs, there's nothing listening on 443. I don't think that will be an issue for anyone, but let me know. Even if it is, however, it can be changed in the .env as JQUERY_WP_HTTPS_PORT to 0 to get some random, unused port.

I've left comments indicating the issues, but those are solvable.

Out of curiosity, what is the reason for preferring HTTPS locally? Does it allow better testing of certain pages?

We talked about it a bit in chat. Essentially, my security settings (mainly my VPN), make it difficult to allow non-https anywhere but localhost. The settings are admittedly aggressive, but it's easier to support it here than it is for me to change it. Also, there are advantages to being able to test these sites locally with https. In the immediate future, it will come in handy when testing CSP changes.

I confirm setting JQUERY_WP_HTTP_PORT works so I have no further reservations against this PR.
