I ran the versions script to create a snapshot version.
When I run yarn run start, I see my website with a new link at the top for versions. Clicking that link leads to a page not found.

Upon checking the website/pages/en folder, I don't see a versions.html file.
I found a workaround:
$ yarn examples versions
Creates the versions file.
We should probably check for a versions.js file and do not run the server if it doesn't exist. We may do that already, I will need to check.
