electronuserland/builder uses yarn 1+. Should we upgrade to 4?

I wonder if we should upgrade to yarn 4.

I'm not blocked because I can use this modified version of the electronuserland/builder: 

```
FROM electronuserland/builder
RUN npm install -g corepack
RUN rm -f /usr/bin/yarn
ENV PAHT="$PATH:/usr/local/bin"
```

Thank you so much for supporting the multi-platform build. Such a killer feature.
