Description

Find functions with appropriate attributes being set and rewrite them to use @admin.action or @admin.display respectively

https://docs.djangoproject.com/en/3.2/ref/contrib/admin/actions/#django.contrib.admin.action
https://docs.djangoproject.com/en/3.2/ref/contrib/admin/#django.contrib.admin.display

This is going to be a little tricky to do as multiple AST nodes will need inspecting and rewriting at once, if they all match.

We might need to visit class definitions and modules, and check all the function definitions within each + following assignments to figure out everything.

Steps:

• module-level action functions - Add fixer for @admin.action() #178
• class-level action functions - Expand @admin.action() fixer to class-level actions #197
• module-level and class-level display functions - Rewrite admin display function attributes to use @admin.display() #199

Amazing! 🌟

Noticed one thing: This should also work for from django.contrib.gis import admin.

Ah, nicely spotted. I've also added that to the tasks for @admin.register in #190.
