misc: Set package manager to yarn v1

[krystofwoldrich]

Since RN 0.74 the default RN template uses Yarn v3, when running e2e tests, this might cause issues as yarn will try to upgrade to v3 in the repo root.

This PR sets the yarn version to v1 in the repo root to avoid conflicts with newer yarn versions.
