l10n: README: call more attention to plural strings

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.
