* Removed wrong information about container DNS
In the docs it says a container will inherit the host /etc/hosts file along with /etc/resolv.conf. While the latter part is correct, /etc/hosts will not actually be inherited, as reported https://github.com/moby/moby/issues/39311.
An additional line of text has been added to emphasize the fact that /etc/hosts are not inherited
* Removed extra hash on the run command redirect
* Update config/containers/container-networking.md

### Background
Newer upstream PostgreSQL Docker images, now require a password for use. If you were previously using passwordless access to a PostgreSQL DB, it will likely fail with an error.
This linked GitHub issue showcases the error:
https://github.com/docker-library/postgres/issues/681
### Solution
The postgres docker page gives instructions on how to use the new image : https://hub.docker.com/_/postgres
There seems to be two different options we can take here :
Option 1 - Implement a password using the environment variable
Option 2 - Revert back to old behavior of having no password requirement
### Thoughts
Based on the team members remark it looks like increased security was the major reason for this breaking changing happening in a minor update. Refer to this comment : https://github.com/docker-library/postgres/issues/681#issuecomment-586517154
As such I opted to use Option 1 here in this change as increased security of a DB is generally a win for every one in most cases.
