Unlike GitHub's web-UI, the "rouge" hightlighter used in our
online documentation is case-sensitive. As a result, code-blocks
having the Dockerfile (uppercase) code-hint were not highlighted.
This changes those to use lowercase, which is supported by both.

Since CLI was moved to a separate repo, these references are incorrect.
Fixed with the help of sed script, verified manually.
