Summary:
This doesn't change the website for now except that, if you can guess
the URL, you can now access /docs/next/<page> and /docs/0.17.0/<page> in
addition to /docs/<page>. This is all automatically handled by
Docusaurus, nice!
We still need to manually version static/man/ and static/odoc/. The
0.17.0 versions are now in static/man/0.17.0/ and static/odoc/0.17.0/.
I haven't created static/man/next/ and static/doc/next/ (corresponding
to the "next" version) yet so some links in /docs/next/ are dead (but
unreachable by visitors for now). A follow-up commit populates these
with the man pages and odoc for the current master via an updated
`make doc-publish` target (it's currently regressed to a broken state).
