[Bug Report] Simple install with [all] option fails without swig

[kwinkunks]

Describe the bug

The README says

use pip install "gymnasium[all]" to install all dependencies

But I think running pip install "gymnasium[all]" in a clean Conda environment (with Python 3.11) fails without install swig first, because box2d-py will not build without it.

I guess the problem lies with the box2d project, who should specify that it is required in their build process, but possibly the README be updated to reflect this requirement?

Similar to #735 and #632, but for [all] option, not [box2d].

Not sure how best to proceed, so won't make a PR.

Code example

conda create -n foo Python=3.11

Then, when complete:

conda activate foo
pip install "gymnasium[all]"

Results in (eventually):

Running pip install swig first solves the issue.

### System info

Installing with `[all]` option using `pip`.

Gymnasium v0.29.1, MacOS v14.1.1, Python v3.11.7.

### Additional context

Thank you for maintaining this project!

### Checklist

- [X] I have checked that there is no similar [issue](https://github.com/Farama-Foundation/Gymnasium/issues) in the repo

[kir0ul]

The strange thing is that [all] should already install Swig: https://github.com/Farama-Foundation/Gymnasium/blob/main/pyproject.toml#L63. Same for [box2d]: https://github.com/Farama-Foundation/Gymnasium/blob/main/pyproject.toml#L39. Maybe there's an issue of chronological order, like Swig needs to be installed before building the box2d wheel? 🤔

But conda install "gymnasium[all]" seems to work seamlessly, maybe it should be added to the README as well?
(Indeed AFAIK, when possible, it's recommended to avoid mixing Pip and Conda packages: https://www.anaconda.com/blog/using-pip-in-a-conda-environment.)
