awx_task container vs awx_web container

Page 330 begins with instructions to repeat the 5 steps, this time in the awx_task container.
However, the instructions point to the wrong container: `docker exec -it awx_web /bin/bash`, which is the same as the one for the previous steps.

Open page 330 and compare the five steps for the awx_web container with the repeated steps described for awx_task. Check the documented docker exec command and update the container reference so the instructions match their stated target, then review the page for consistent wording.
