fix: re-pull Atlas translations for mounted edx-platform

The new Atlas-based translations system stores important
translations artifacts in edx-platform.

Unfortunately, when edx-platform is bind-mounted, these
translations artifacts are overwritten. This means that
edx-platform developers will see 404s on various i18n-related
assets in Django-rendered LMS and CMS pages.

We work around this in the same way we do for static assets,
egg_info, and node_modules: Just re-generate the translations
artifacts as part of the dev init job. This is a waste of time
and bandwidth, but it's the system we have, for now at least.
