As of #406, the template and linting now insists that the Dockerfile uses a tagged version of the nfcore/base image in the FROM statement.

This is fine, but means that the minimal working example needs to be updated every time we change the tools version number:

At the moment we're hacking the solution by manually bumping the version in the tests. But this could also be annoying for devs running the dev version of the lint tests, as this will mean that tests either locally or on Travis will fail.

Needs a better solution... 🤔
