@amoore108 Do the docker images for CI need to be updated? (I think they might actually be OK, but wasn't sure if we should check on the preview environment first?)

Could be worth checking on Preview, but I feel like minor updates should be ok. We updated Cypress to a newer minor version than is on its Docker image and it seems ok.

Let's test this on the Preview pipeline to make sure that it is still compatible with the yarn 4 docker images.
