docs: update code-hints for compatibility with "rouge"

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.
