[python/django] remove use of "builds" (#905)

### Description

We don't want to encourage the use of `builds` in `vercel.json`. This PR
updates the `python/django` example to not use `builds`.

I tested manually deploying this example and it worked for me.

### Demo URL

https://django-qqienvle1-uncurated-tests.vercel.app/

### Type of Change

- [ ] New Example
- [x] Example updates (Bug fixes, new features, etc.)
- [ ] Other (changes to the codebase, but not to examples)
