Fix local docker setup to add support for yarn v3 (#905)

Yarn v3 needs:
- activating inside Dockerfile
- volumes need mounting in docker-compose

### Notes

- `yarnrc.yml` could be different between environments (i.e. local
machine and container) so ignoring the file in the repo and generating
one on build in docker
