[Translations] allow updating type in relation to key not locale translation #1285
Description
You can see below that all translation updates are made focussing around a specific locale i.e. 'en'. The type update is in reality across all locales.
With the current API set up, this means that when updating the type I have to use an arbitrary locale (I am using the first in line) and send the updated type nested inside the locale.
It would make sense to allow updating the type based on the key without having to add any translations in the update.
