As of flutter/packages#12119, material_ui and cupertino_ui each have an l10n directory with its own README explaining how to generate localizations for the package. However, this uses shared scripts in script/l10n that has its own README. Instead of duplicating this messaging across the two package READMEs and keeping the script README barebones, perhaps we should have one generic set of instructions in the script README and just refer to that from the two package READMEs.
