Update peer dependency version
Hello! Thank you for the nice icons.

I have switched to npm 7 and it installs peer dependencies by default. So when I updated Vue to `3.0.11` I got a conflict with `phosphor-vue`'s peer dependencies:

```
  "peerDependencies": {
    "vue": "^3.0.0 <3.0.3"
  },
  ```

Could you, please, change it to `^3.0.0` and make a new patch release?
Right now I can run `npm install` only with `--legacy-peer-deps` (when there is no `package-lock.json`).
