Pull Request Checklist for MontePy

Description

This a quick documentation fix to make the jupyterlite notebooks work. This is an issue I forgot to open. Basically piplite (the tool used by jupyterlite) installs via a background async job. So the current way of installing montepy doesn't wait for the installation to complete before trying to import montepy. This fixes this by finding the synchronous runner provided by pyodide. It maybe janky code, but it seems to work. I also went through and fixed some broken doc strings, changelog formatting errors, and all of the URLs in the Demo notebooks.

Fixes #863

I'm thinking of doing a post release to push this to stable on RTD. Probably skip releasing on PyPI though.

Ok now all URLs are updated and correct.

I am going to go and merge with it being a busy time of year, and this being just for documentation, and for the existing documentation being broken.
