Configuring Automated Builds in Understanding Docker Hub chapter: Indicated Build Context path needs to be updated so the build succeed

[bougwal]

Reference: page 81 paragraph 2, line 10 in the configuration of the automated builds steps (step 3).

The indicated path in this edition for the build context is: "./chapter02/dockerfile-example/".
This will cause the build to fail with the message:
Dockerfile not found at ./chapter02/dockerfile-example/./chapter02/dockerfile-example/

To succeed I did the following:

1. I set the Dockerfile location to: /chapter02/dockerfile-example/Dockerfile
2. left the build context empty.
