Explore github pages redirects

[frankharkins]

We'll need to test redirects with GitHub pages in a fork before publishing them from this repo.
See the docs here: https://docs.github.com/en/contributing/writing-for-github-docs/configuring-redirects#configuring-external-redirects

If that doesn't work, we can always add a HTML redirect to index.html.
