Yarn v2 compat: add vue to peerDependencies

[AlexandreBonaventure]

Version

3.1.2

Steps to reproduce

When using Typescript, vuex export types like here: https://github.com/vuejs/vuex/blob/dev/types/index.d.ts#L1 But as you can see here, it imports Vue typings to make it work. As a matter of fact vue should be added to peerDependencies

What is expected?

vue should be a peerDependency

What is actually happening?

it is not, and it fails in a strict dependency-tree context

Ref: vuejs/vue-cli#5135

Thanks for the report! Yap, indeed we should have it as a peer dependency. PR on the way 👍
