Default state dropdown to empty

[porter-stripe]

Summary

• Instead of the "State" dropdown defaulting to selecting the first in the list (Alabama) we now default to no selection so users are forced to select a state to prevent accidental completions without selecting a state.
• Applies to Address Element and PaymentSheet

⚠️ Missing Translations
The following strings have been uploaded to Lokalise but are not yet translated.

Selection is empty.

If it's okay for these strings to be unlocalized in master (e.g. this is for an unshipped feature), add the label ship without translations to acknowledge that there are missing translations. Otherwise, wait until translations are available in Lokalise and re-run this job.

New strings are localized on a weekly basis and are downloaded as part of the release process. For more details on how to localize a string, you can refer to this link.
