frontend: CreateNamespaceButton: Fix malformed i18n interpolation

The interpolation used non-standard spacing ({{  newItemName  }}),
which generated duplicate translation keys during i18n extraction.
Normalize to {{ newItemName }} to match the rest of the codebase and
drop the redundant locale entries from all 16 locales.

Fixes #5918
