Update dependencies for Snyk scan

[giulio-giunta]

What did you expect?

Snyk should not fail, both the PR check and the cicd pipeline.

What actually happened?

Snyk fails the PR check and the cicd pipeline because of an outdated version of Django. Also, the "development" Dockerfile has an outdated version of Python.
