chore: update to jest 27

Updates jest, ts-jest and babel-jest to v27.
vue-jest v5 does not support jest v27,
so a new vue3-jest package has been introduced (see vuejs/vue-jest#343),
with a version number aligned on the jest version (as ts-jest and babel-jest do).

This commits replaces vue-jest by vue3-jest, and updates the jest config to use this new trasnformer.
This will be the default Vue CLI setup in the future.
