releases: Add @vue/test-utils and Jest
Why:
- An increasing number of projects using Vue.js and Codex are adopting Jest for testing. As of this MR, 20 repositories[1] depend on @vue/test-utils and 40 on Jest.[2]
What:
- Add releases for @vue/test-utils, jest and jest-environment-jsdom to allow libup to automatically keep these packages up-to-date.
