function _install_config_locale_overrides

Creates a batch to process config translations after installing from config.

This ensures that the logic from LocaleConfigSubscriber::onConfigSave() is run on sites after installing from configuration so updating translations from PO files does not result in overwriting customizations.

Return value

array The batch definition.
