environment_level_auth_configuration resource

[mrmauer]

Blocked on this PR

After PR

This creates a propelauth_environment_level_auth_configuration resource that allows practitioners to manage auth-related behaviors that are specific to the environment (ie test/staging/prod) rather than global to the project. The most common examples being

1. whether email confirmation is required
2. whether public signups is available

Still Need

• write example uses including the need for dependencies on domain verification for prod/staging environments

Tests

New acceptance test for this resource that pass locally. They will fail in CI here until we ship the PR above.
