Hi us ;),

Looking through our Downloads page, there doesn't appear
to be a super obvious "Docker" image to point people at.

eg, the OS list has:

   * Linux
   * macOS
   * Windows
   * BSD
   * Solaris

Should we add Docker there too (with useful info), as it's
kind of OS agnostic?

Or am I just not noticing something obvious? :)

For reference, there are PG docker images which seem to be
well regarded (AFAIK):
