Update App config defaults

[NoelDeMartin]

I'm opening this PR as a draft because until v4.4.0 of the app is released, these defaults don't work with the moodlehq/moodleapp:latest-test image, which is the default (they only work with moodlehq/moodleapp:next-test). But we can get the review started so that once 4.4.0 is released, we can merge this.

moodle-docker has a similar issue, but given that we explicitly support different versions, I've implemented an interim solution in moodlehq/moodle-docker#281.

But for moodle-plugin-ci, I think it's fine just to support one version out of the box. And anyone can configure old versions if they want using other env variables (the documentation has also been updated).

Thanks @NoelDeMartin ,

really, there is something with the relations between MOODLE_APP_PORT, MOODLE_APP_PROTOCOL and MOODLE_BEHAT_IONIC_WWWROOT that I'm unable to understand completely, but, hey, that doesn't matter much for the purposes of the PR.

So, as far as it's all passing, I'm ok. I imagine that 99% of people really only needs to enable MOODLE_APP and that's all.

Ciao :-)
