Improve documentation of image (password + link to neo4j docker documentation) about docker-neo4j

@callicles thanks for bringing it up here.

Just to make sure we are talking about the same things, the README does link to that page under Documentation at https://hub.docker.com/_/neo4j/:

If that IS the page you are talking about, would you consider it a fix if this link was easier to find in that wall of text?

Interesting, I was not looking through dockerhub but through the store https://store.docker.com/images/5f0be9a7-f5d7-4974-9c0e-78c33484e79c.
On that page there are broken links that are supposed to point to the documentation.

Oh! That store page must be built from an out-of-date Docker hub page. Maybe it is a Docker problem after all. I'll take this back to them. Thanks for reporting this.

@callicles the store page has now been updated to match the docker hub page:
