I don't know anything about Yarn's CI cache, but I can see that packages/prisma/.yarn/ci-cache/install-state.gz is in a ci-cache directory, and it is tracked in git. This file is ~4MB, and is making the repository absolutely huge.

There are other files too in packages/**/.yarn/ci-cache.

Should these file be removed from git, to stop the repo growing unnecessarily? I'd also suggest a git filter-branch to remove it from history, but I understand that's a hassle due to the history rewriting.
