Description of change

Newer versions of Redis (>= 6.0) have introduced new authentication errors, which are currently not handled in redis-py:

• "-ERR AUTH called without any password configured for the default user. Are you sure your configuration is correct?", instead of "-ERR Client sent AUTH, but no password is set"
• "-WRONGPASS invalid username-password pair or user is disabled." instead of "-ERR invalid password"

In these cases a ResponseError was raised, instead of an AuthenticationError.

Closes #2325
