add instructions for https when running meili in docker

[tacman]

This page is very helpful for running meilisearch with docker:

https://www.meilisearch.com/docs/guides/misc/docker

But it runs without https, simply on http.

I'm trying to use view my data with a dashboard utility at https://meilisearch-ui.riccox.com/ but it requires that the server be running https (CORS issue, I think).

Can you document how to do that please?

Thx.
