Caused by 90c4e2e6ec.
We are now getting the enum item via
`RNA_property_enum_item_from_value_gettexted` (as opposed to
`RNA_property_enum_items_gettexted` prior to 90c4e2e6ec).
The former does not translate the description (whereas the later does)
which I think is just an oversight.
To resolve, now add description translation to
`RNA_property_enum_item_from_value_gettexted`.
