fix: django admin wasn't showing details of content libraries (#38578) [Verawood Backport]

[MaferMazu]

Problem

When we enter the Verawood sandbox in the Django Admin and try to check a specific content library, the web returns a 500 error.

Link in Django Admin: https://verawood.demo.edly.io/admin/content_libraries/contentlibrary/
Link with the error 500: https://verawood.demo.edly.io/admin/content_libraries/contentlibrary/1/change/

You can test the error with the sandbox credentials: https://docs.google.com/spreadsheets/d/1j1uDhVIVLwHUfrMLBzx6lM55gYL6i4nUqbzkbLHpaHQ/edit?usp=sharing

The problem was introduced in this PR #38297 when we removed the authorized_lti_configs field, and it was solved in #38578.

Description

This is a cherry-pick of #38578

Why this should be in Verawood

To not have that view broken. An admin user should be able to see their libraries in the model.

Notes

I tested in a verawood env and worked as expected. You can test it using this branch, and enter it in yourlms/admin/content_libraries/contentlibrary/1/change/ (you should be able to see the library details and not get a 500 error)
