The patch was meant as a quick temporary work-around to have the docs
built and published.
Now that releases where -W flag is set (turning warnings into errors)
are appropriately patched to make those warnings disappear (on Sphinx
v3.2.1 which is the one used on the builder), this patch can be reverted
so that next time a warning appears the doc building will fail but will
not destroy the doc website (because of commit
6a4e6ef18d "scripts: run-docs-build: make
the script fail hard ASAP when there's an error", since rsync will not
be run if any error happens before).
This reverts commit 931d409b25.
