⚠️ Missing Translations

The following translations are missing in Lokalise. While they don't need to be downloaded into the codebase as part of this PR, they do need to exist in Lokalise so that they can be downloaded as part of the release process.

This is not in lokalise translated, This is not in lokalise translated2

By adding the label ship without translations to this PR, I acknowledge that there are missing translations.
