Although our documentation is rendered for the "in the box" docs by
cmark-gfm, the upstream docs site (docs.npmjs.com) uses mdx, which is
a much stricter parser.  Update our docs generator site to ensure that
mdx can parse our documentation as well, to ensure that we get fast
feedback when it would fail.

If the user has specified a silent loglevel, we should pass that intention on
when we call runScript

Also a small cleanup in lib/run-script.js so that the reference to
@npmcli/run-script is named the same as other files.
