i18n: Update translation catalogue

Update the translation catalogue to pick up two new translatable phrases
and provide the English translations.  pt_BR already has the
translations but zh_CN will need to be updated.

The new phrases are:

msgid "Please create a template first."
msgid "Create a Template"
