Rewrite Regression Notebooks to easily display them on the page

[dBCooper2]

Currently the mix of markdown and LaTeX within the notebooks found in the tr-dev project breaks when the project tries to render it. Separating the Notebooks into discrete Markdown and LaTeX-only blocks should fix this, so MathJax and the Markdown renderer are not competing with each other in the rendering.

The fix I found was writing a custom component(with ChatGPT's help...) that wrapped a ReactMarkdown component in some highlight.js custom CSS to render the code blocks. This is working now, and all that needs to be done are some CSS changes to make the page a little prettier
