⚠️ 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.

Update, Update card brand

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

[porter-stripe]

@yuki-stripe translations are in, the "Check Missing Translations" check is passing w/o the "ships w/o translations" label. They'll be downloaded in the next release in the proposal PR.
