Vue 3: Cannot resolve "@vue/vue3-jest" module. on GitHub Actions

Question

When running my unit tests in GitHub actions after upgrading to Vue 3, I get the following error:

> vue-cli-service test:unit

● Validation Error:

  An unknown error occurred in @vue/cli-plugin-unit-jest:

  Cannot resolve "@vue/vue3-jest" module. Please make sure you have installed "@vue/vue3-jest" as a dev dependency.

The GitHub actions script uses npm ci as its previous step to install dependencies, and the test command vue-cli-service test:unit works locally.

My package.json has:
