Looking into the Type check CI, maybe this should be able to fix the issue :)

I think this is currently blocked by the publication of v3 for unity-builder: https://github.com/game-ci/unity-builder/releases

Will we also need to bump unity-test-runner?

Correct. I'm waiting for a review and then I'll double check and do the release

Probably a good idea yea. We'll have to bump to 4 for the CLI integration anyway.
