Ref: pnpm/pnpm#4475

Note: git-branch-lockfile is the config, not use-git-branch-lockfile 😅

Imagine this scenario:

1. master branch has pkg-a that depends on react 17 & react-dom 17
2. on feature-1 branch, developer upgrades pkg-a's dependencies: react 18 & react-dom 18 this creates pnpm-lock.feature-1.yaml
3. feature-1 is merged to master branch
4. on master branch, run pnpm install --merge-git-branch-lockfiles

1. Clone this repo
2. Run pnpm install --merge-git-branch-lockfiles
