Rails 7.0 Support

The primary change for this release is support for Rails 7.0, with one breaking change.

• Using #encrypted_attributes is no longer supported. Instead, use #attr_encrypted_encrypted_attributes to avoid collision with Active Record 7 native encryption.

Dropping support for Rails 3 and 4

Support for Rails 3 and 4 was dropped as part of this release.
