compatibility with rich 15.0.0

Nobody has claimed this yet.

### Bug description

Hello

I would like to install `lightning[pytorch-extra] 2.6.5` and `rich 15.0.0` in the same python environment
But when I run `pip install lightning[pytorch-extra]==2.6.5 rich==15.0.0` I have this conflict :
```
The user requested rich==15.0.0
lightning[pytorch-extra] 2.6.5 depends on rich<15.0 and >=12.3.0; extra == "pytorch-extra"
```
Would it be possible to ensure a compatibility with `rich 15.0.0` ?

By the way, I can't find the requirement file, or setup.py file, or pyproject.toml file from which comes this constraint `rich<15.0`...

Regards

Start by locating the packaging metadata that defines the `pytorch-extra` dependency for `lightning==2.6.5`, then inspect why it restricts `rich` to versions below 15. Reproduce the reported `pip install lightning[pytorch-extra]==2.6.5 rich==15.0.0` conflict and confirm that the updated constraint permits both versions.
