Fix this deprecation warning:
DEPRECATION WARNING: ActiveSupport::TimeWithZone.name has been deprecated
and from Rails 7.1 will use the default Ruby implementation. You can set
`config.active_support.remove_deprecated_time_with_zone_name = true` to
enable the new behavior now.
Triggered by the XML serializer in the API.
* Update framework files with `bin/rails app:update`.
* Update to use new Rails 7.0 default settings, except for a couple
things regarding new cookie and cache formats that would prevent us
from rolling back to Rails 6.1 if necessary.
