Add initial Dockerfile and devcontainer configuration (#645)

In the past the devcontainer was not working out of the box in the process description.

Now, the copied file from score repo into process_description and trying  e.g. bazel run //:docs runs out of the box.

It makes sense that others take a look, if it works for you as well.

This is meant as a proposal as it could be worth to align to the standard S-CORE container.
