fix(python-deps): added missing dev group dependencies (#5708)

# What does this PR do?
Adds missing dependencies to `dev` dependency group, making the new
developer experience better.
CONTRIBUTING.md file will work (copy & paste)

 Closes #[5631]

## Test Plan
To simulate a new developer experience, get a fresh docker container:
```
docker run -ti python:3.12-slim bash
```

And then, add the tools needed to clone the repo and add the `.env` file
(my choice is vim):
```
apt update && apt install -y git vim
pip install uv
git clone https://github.com/ogx-ai/ogx.git
```
and then continue with the [CONTRIBUTING.md
line-by-line](https://github.com/ogx-ai/ogx/blob/8fcda2fafcd000f489d812665876cdfc769f3876/CONTRIBUTING.md?plain=1#L11-L42).

-> This currently fails on `master` branch with `ModuleNotFoundError`.
