Remove redundant Spanish overrides for product name localization keys (#2348)

The %product_name% and %product_shortName% entries in es.json were
identical to the English fallbacks, so they had no effect on the UI.
Removing them reduces maintenance noise and simplifies whitelabel
patching: a patch to en.json is now sufficient for all locales that
don't have a genuine translation of the product name.
