Multilingual SRPs

Nobody has claimed this yet.

### What is this about?

This issue is to track internal conversations, user feedback, and potential technical implementation of multilingual SRPs within the MetaMask wallet experience. As we continue to maintain translations of the MetaMask product into 14+ languages, providing capability for multilingual SRPs under BIP-39 would make the wallet more safe, usable, and secure for users whose best language is not English.

Instances of user feedback:

### Scenario

A user who does not read or write English creates a MetaMask wallet, but they struggle to record their SRP accurately. When they go to import their wallet elsewhere, they are unable to because they can't read what they wrote down. Maybe they resort to copying and pasting the SRP, or taking a screenshot instead. If their accounts are hacked, the SRP is easily compromised and their funds are stolen. Providing an SRP in languages other than English means that users are able to record their SRPs accurately and store them securely - which allows them to exercise real self-custody over their assets.
