[scaffold] yarn add epfl-elements-react@file:../epfl-elements-react

... As suggested by the previous commit.

Since we currently don't have a released version of `epfl-elements-react`; but that on the other hand, the [LHDv3 dev kit](https://github.com/epfl-si/lhd3-dev) ensures that `../epfl-elements-react` is available; it just feels better to commit this for now (even if we might incur some commit noise due to checksums changing back and forth between workspaces of team members).
