[PATCH] l10n: README: call more attention to plural strings

[Josh Steadmon <steadmon@google.com>]

In po/README.md, we point core developers to gettext's "Preparing
Strings" documentation for advice on marking strings for translation.
However, this doc doesn't really discuss the issues around plural form
translation, which can make it seem that nothing special needs to be
done in this case.

Add a specific callout here about marking plural-form strings so that
the advice later on in the README is not overlooked.
