A lot of new things have happened in the area of ​​Docker builds in the last few days and weeks. Once all the relevant changes have been consolidated, the documentation should be revised or, if necessary, completely rewritten.

• https://docs.searxng.org/admin/installation-docker.html
• https://github.com/searxng/searxng/blob/master/docs/admin/installation-docker.rst

I created the documentation back then because there wasn't any, and there wasn't any sign of anyone being willing to write it. The problem then was, and still is, that I have no knowledge of the topic.

This time, however, it should be written by someone who does. If he/she have problems with the reST markup (reST primer), I'm happy to correct them in the PR review. It would just be important that the content be written down in some form for the general public (like me).
