Match output to input and clarify build command 

The Dockerfile listed above specifically uses package.json, but the
output listed for the build lists package*, which is inconsistent. The
React example later in the doc uses package*, which would be consistent
with the output, but this should fix the mismatch for the beginner going
through the tutorial for the first time.

Additionally, the sentence "Build the Docker image now using 'docker
build' again" might be confusing to a beginner. I specifically tested
running this exact command and it gives an error message. Specifically
using the exact command needed to build this target shouldn't take up
too much space.

1. Now, make a change to the `src/static/index.html` file (like change the `<title>` to say "The Awesome Todo App").
1. Build the Docker image now using `docker build` again. This time, your output should look a little different.
