Use mkdocs --strict option to verify .md links
Problem/Motivation
We had an internal link in a doc page which had the incorect path.
Fixed in !281 (36ecd8b9)
External links could also be incorrect. Or may be valid at the time of writing, but subsequently the target url is moved or becomes unreachable.
Proposed resolution
Investigate if we want to use markdown-link-check to validate the links in our documentation pages.
