text: Title: Correct all mentions of Py.Cafe
  Body: We have generally referred to PyCafe as Py.Cafe throughout.
  
  I've confirmed with the PyCafe team and they'd rather use:
  * PyCafe to describe their organization 
  * [https://py.cafe](https://py.cafe) to talk about the site itself
  
  The best way to fix this would probably be to grep through the docs content (`vizro-core` only as we don't use it in `vizro-ai` examples) for Py.Cafe.
  
  It would make sense also to add a line to the `Terms.yml` file in the [Vale styles](https://github.com/mckinsey/vizro/blob/main/.vale/styles/Microsoft/Terms.yml):
  
  ```yml
  Py.Cafe: PyCafe
  ```
