User Feedback Prompt (error documentation review request)

[canwaf]

On all of our error code short url web pages, ask whether the explanation is clear, if it helped them fix the problem.

Find out whether we can programatically add a review this documentation prompt in mkdocs. If it's easy, implement it, otherwise create a new ticket.

e.g. https://gss-cogs.github.io/csvcubed-docs/external/guides/errors/build-command-errors/observed-values-missing/
