Update Login.gov config to use biometric configuration

[abroddrick]

Issue description

Login.gov is doing their biometric beta program and we want to participate. For new users, they should go through this new identity verification program, but old users should go through

Acceptance criteria

• "All New Users Require Biometric Flow" configurations changes are made to our oidc setup, thus requiring new users to go through the biometric flow and previous users to go through current idv options
• update unit tests
• remove step_up_acr_value (and any references)

Additional context

slack thread for reference

See the documentation for Biometric configuration and specifically page 4 where it mentions "All New Users Require Biometric Flow"

Notes for dev:
settings.py sets the OIDC_PROVIDERS values which is what controls our login.gov config for both identity sandbox and production. By looking at the documentation it looks like we can leave our ial1 logic alone and then update our logic for step logic. For ial2 we will remove the step up acr value which is no longer needed per their documentation and add vtr and vtm verification.

This ticket was added to sprint 45 on Day 4. Product deemed it a priority ticket. The agreed compromise is to move the WHOIS ticket (cisagov/get.gov#267) to a later sprint.
