Cleanup random Django version support docs (#86)

No code changes, just:

* upgrade dev dependencies
* unify django version specific code comments to be `DJANGO<version>`
* update workflows to use more modern versions


#### Verifying change

* `make build`
* `make run`
* Browse to localhost:8000/admin/
* login with `admin`/`admin`
