Add warning on future breakage

Michal will update tex4ht ditribution... this will eventually make it to
texlive then to the CI server and it will break.  Adding his comment in
the code so we know.

-If you're a hobby brewer, you'll know that it's important to keep your beer at
-certain temperatures to allow the different amylases to convert the contained
-starches into sugar~\cite{beer+amylase}.
-This test, called the \emph{Iodine Starch Test}, involves mixing iodine into
-a sample of your brew and checking the color.

+% Warnig from Michal: Note that once you get the updated TeX Live with a new
+% `chemfig.4ht` file, you can remove this from the config file:
+%
+%```latex \pend:def\schemestart{\Picture+{}}

+%
+%You could get an error otherwise, as there would be nested `\Picture+{}` and
