- Restore the v2_key

Cherry picked from commit 8529571:
- Drop config.assets since sprockets-rails isn't in rail 7

Cherry picked from commit c716815:
- Temporary override of the belongs_to_required_by_default setting

Cherry picked from commit 6b7d6fd:
- Update the dummy app to use_yaml_unsafe_load in rails 6.0.5.1
