Unknown third-party extras

<!--
Hi there! Thank you for wanting to make fpdf2 better 😉.

Please perform a quick search first, in order to check if your problem has already been reported:

Installing the package warns about unknown third-party extras.

**Error details**

> WARNING: camelot-py 1.0.9 does not provide the extra 'base'
> WARNING: endesive 2.19.3 does not provide the extra 'full'
> WARNING: bleach 4.1.0 does not provide the extra 'css'

* *camelot-py* removed the extra in 1.0.0 (https://github.com/camelot-dev/camelot/commit/9707effebddc6aed0661e8d8079ce5a5e6fa0b23) (By the way, Ghostscript is now a dedicated extra for licensing reasons and thus the development guide a bit out of date.)
* *endesive* removed the extra in 2.19.3 (https://github.com/m32/endesive/commit/a7f9332978767b42fc4bb95442f42167c40ee581)
* *bleach* comes from `nbconvert>=6.0.0->mknotebooks->fpdf2==2.8.7` and thus most likely cannot be fixed from the *fpdf2* side

**Minimal code**

```bash
git clone git@github.com:py-pdf/fpdf2.git
cd fpdf2
virtualenv venv
source venv/bin/activate
pip install --no-cache .[dev,docs,test]
```

**Environment**
Please provide the following information:
* **Operating System**: Ubuntu 24.04
* **Python version**: 3.12.3
* **`fpdf2` version used**: https://github.com/py-pdf/fpdf2/commit/90aa3f41c730514560766daedcac639caf0e4ee5
