Docker Image Broken

[mikesmitty]

Looks like the tailing dev section on the Dockerfile is breaking the build. After removing that section the container builds and runs fine.

Thanks for pointing this out! I clearly messed up the build action. Will fix later tonight.

@mikesmitty I believe this should be fixed with the latest commit.

Mdns-tunneller uses Docker's multistage builds. There is no need to delete the dev section, but rather specify the prod target: docker build --target prod -t mdns-tunneller . I've fixed the github workflow file so the :latest should have the prod target now.
