Generate documentation before running link check (#78)

* Generate documentation before running link check

Some links may point to the generated documentation content, which would result in a failure of the link check.

It's true that these links are indeed broken when accessed outside the website, but the primary publishing location for
this content is the website. The alternative would be checking the generated content into the repository, but this would
either require some fairly complex automation or else a burden on the contributors to keep it synced.

* Use relative link to command reference in docs

It's important to use relative links so that the user's website version selection is retained.
