Symfony version(s) affected: 4.3.1

Description
Previously encoded passwords with argoni2 algoritm are not verified by Symfony 4.3, although they could be automatically

How to reproduce

• Install fresh symfony 4.3 with simple user management (ex. FOSUserBundle)
• Use algoritm argoni2 instead of auto
• create user with hashed password
• switch algoritm to auto
• can't login anymore

Possible Solution
Very similar to 1318d3b

if (0 === strpos($encoded, '$argon2i')) {
  return password_verify($raw, $encoded);
}

Additional context
Related to #31758, but made new issue because it was already closed and target to bcrypt. I'm having the same issue with argoni2
