The link to fosdem.org is inlined but also included in the footnote [#c].
Replace the inline link with a reference to the footnote, because Sphinx
8.1.0 is a lot stricter about unreferenced footnotes.

I think for this doc, because all the footnotes are
simply URLs it will produce a better HTML document if
we instead convert them all to hyperlinks in line.
At the moment you have to click on the footnote link
and then again on the URL.
