[Test Case]
Deploy openstack with magnum + magnum-ui. Ensure dashboard is functional and no errors in /var/log/apache/error.log.

[Regression Potential]
This is a pretty simple change to aliased functions and regression testing mentioned above should be good enough to ensure behavior is as expected. Currently the dashboard doesn't work on Mantic where Django is at 4.2.4. This package is backported to the Bobcat cloud archive on Jammy where Django is at 3.2.12 and will need testing there, however should be fine considering these functions were deprecated in Django 3.0.
