Use root-dir instead of base-url in CI (#111)

* Use root-dir instead of base-url in CI

root-dir is the right argument to use to check a directory of local files.

* as above, for check-links.yml

* we want to checkout the merge ref in a pr

* we need to fetch the ref first because it isn't a normal branch
