mgr/dashboard: Update translation

Updates the following translations:

- Czech
- German
- Spanish
- French
- Indonesian
- Italian
- Japanese
- Korean
- Polish
- Portuguese (Brazil)
- Chinese (China)
- Chinese (Taiwan)

I committed directly to the nautilus branch, because the differences of the
translation files between master and nautilus is too huge. We also track the
translations for each ceph version as a seperate resource on transifex.
