Upgrade Rails to 7.2

[caitmich]

Summary

Upgrade Rails to 7.2:

• Use named arguments in serialize: calls
• Wrap active_record.yaml_column_permitted_classes in an after_initialize block
• Update config.action_dispatch.show_exceptions to use new :none value

I assign all rights, including copyright, to any future Dradis
work by myself to Security Roots.

Check List

• Added a CHANGELOG entry
