[Wallet] Validate mnemonic in the app's language

[gnardini]

Description

Validating the mnemonic was defaulting to english, so it was not possible to restore accounts created in Spanish or other languages.

It is possible now to restore in Spanish, but only if the app's language is set to Spanish. I wonder if we could do something smarter and figure out the language of the mnemonic based on the first word/s so we don't depend on the language chosen by the user.

Tested

On the simulator

💯 Thanks for fixing this critical issue!

Great catch! Would love to get this in 1.2.0 if the issue was actually that any non-English mnemonics were resulting in errors.

Can we please add some copy to explain to the user that their app language must match their mnemonic language? That should help mitigate that confusion for now.

Tested on both iOS and Android just in case and everything looks good. Great work :)

@Lss-Ankit Thanks for testing this! What you see is expected, this change makes it so you can only use an account key of the same language you chose for the app. So, if the app is in Spanish you need a spanish Account Key. To create one, you need to create an account with the language as spanish and the created account key will be in spanish.
