When pulling the main branch the npm packages won't install with npm install due to a number of conflicting dependencies around react.

After closer inspection of the failing packages, it turns out that the packages causing the error aren't even in use anywhere. Specifically:

• "@mdx-js/runtime": "^1.6.22"
• "gatsby-plugin-use-query-params": "^1.0.1"
• "react-katex": "^2.0.2"
• "react-rangeslider": "^2.2.0"
• "react-scroll-up-button": "^1.6.4"

With the changes in this forked branch both npm and yarn are able to complete and run both develop and build successfully.

Still a lot of other outdated packages, etc. but at least it runs.
