[docs] [Announce] PDF downloads are back on tracks

[Julien Palard]

Hi everybody,

Thank you for reporting!

The downloads link are now fixed (don't hesitate if you find an exception, to send me the exact link that does not work).

If you're interested in fixing the root cause, it's probably due to: https://github.com/sphinx-doc/sphinx/issues/5561

In the meantime I used a temporary fix to make the builds work, so it should be OK now \o/

Sorry for the inconvenience :-(
