Why
Dependabot's corepack yarn install --mode=skip-build was failing with RequestError: getaddrinfo EAI_AGAIN classic.yarnpkg.com because four git-hosted fork dependencies have Yarn Classic yarn.lock files — when Yarn 4 repacks them in a clean clone (no .yarn/cache), it detects the missing __metadata key and tries to bootstrap Yarn Classic by downloading https://classic.yarnpkg.com/latest.js, which times out in the restricted network.
See https://github.com/overleaf/internal/pull/33420 for more context
What changed
This PR adds "packageManager": "yarn@4.x" to each fork and regenerates the yarn.lock
