So the update for this doc snippet updating two things:
1.) Decoding the user password hash
currently we don't so when a dev performs import the password hash is getting double encoding leading to invalid password errors when the correct password is provided for a newly imported user
2.) Updating the decoding functions so the hash.Scrypt key uses standard base64 encoding and user password hashes uses base64URL encoding
currently the snippet doesn't decode the use password hash, but it should using a base64URL encoding
Developers are having trouble migrating users because of the issue described here. This update looks to update the snippet used in https://firebase.google.com/docs/auth/admin/import-users#import_users_with_firebase_scrypt_hashed_passwords to help users migrate users and avoid issues surrounding double base64 encoding.
