Sebastiaan van Stijn 90b60b5d88 Dockerfile.dev: set prompt, add nano and jq, and set MOTD ...

This makes some minor improvments to the dev container:

- add `nano` as an alternative to `vi` to help beginning contributors, or people
  that don't remember how to quit `vi` ;-)
- add `jq` as it's often handy to have available to debug JSON output.
- set a custom prompt to make it clearer that the user is in a container
- add a short MOTD that shows that the user is in a container, and a pointer
  to 'make help' (we can add more help/instructions to this MOTD in future).

Before this patch:

    make -f docker.Makefile dev
    ...
    bash-5.1#

With this patch:

    make -f docker.Makefile dev
    ...

    You are now in a development container. Run 'make help' to learn about
    available make targets.
