Fix creation of records for Rails 7.2 version

[w-zygmuntowicz]

Fixes #174

I'm not sure what's going to happen when someone is using the audited gem besides the audits provided by the motor-admin gem. Is the initializer a good place to go? Maybe a better way would be to create a generator which would be triggered during update and/or installation of the motor-admin gem with additional messages for end users?

Regarding the change in the fetch_configured_model.rb file, this one failed when using the Rails 7.2. That was because klass.reflections had keys which were strings, however klass._reflections should have symbolized keys in Rails 7.2.

Edit:

Regarding the audited issue. Maybe event better alternative would be to configure the class as an abstract class on and off inside a transaction? That way the behaviour would be benign, the end user wouldn't have to worry about the audited issue at all.
