Fix Redis compatibility with boto3

[axelstudios]

What's this PR do?

Downgrades django-redis for compatibility with boto3 to resolve this error:

Requirement already satisfied: boto3==1.34.42 in c:\nrel\seed.clean2\.venv\lib\site-packages (from -r requirements/aws.txt (line 2)) (1.34.42)
ERROR: Cannot install django-redis==5.2.0 and django-redis==5.4.0 because these package versions have conflicting dependencies.

How should this be manually tested?

pip install -r requirements/aws.txt should succeed
