Investigate intermittent Vercel deployment failure

[mikehardy]

Issue

Current main branch is intermittently failing on Vercel

You may detect this by looking at the commit history of the repository and looking for the green checkmarks or red Xs per-commit, you will see quite a few red Xs and if you hover over them to get details you'll see it is the Vercel deployment failing.

Sometimes it works though, with no change to the related code or dependencies, so it is intermittent

I reproduce it locally though, when running the commands that fail:

1. cd website
2. yarn
3. ``yarn run build`

First time it happened was 6 days ago, it has been intermittent but worsening since then. Not sure what changed in the dependency graph unfortunately and just verified that the dependencies there are not locked so something must have slid out of a compatible range 😬
