FBReactNativeSpec Cocoapods lockfile has a different hash across machines

Please provide all the information requested. Issues that do not follow this format are likely to stall.

Description

On iOS, after running pod install, Cocoapods creates a Podfile.lock. The lockfile should be checked into Version control to lock down the Cocoapods dependencies.

When committing the lockfile and running pod install on a different machine, the hash of FBReactNativeSpec changes.

- FBReactNativeSpec: 2323960c2c1cb6cf3e4072c3bc18376710f25425
+ FBReactNativeSpec: d27c8ab318553f4c49f992b63504f1e06b44235b

I am raising this issue because for teams, this is a small annoyance, since you always have to either commit the hash change to an unrelated pull request or manually discard the change.
Therefore I wanted to ask if it's possible to investigate it and find a fix that causes the lockfile hashes to be reproducible across machines.

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Run pod install on one machine and commit the Podfile.lock
2. Run pod install on another machine and observe that the lockfile has changed.

Expected Results

The lockfile should stay the same to the Git status stays clean

As far as I know, this is reproducible on any React Native project.

A fix is discussed here and has been suggested as a cherry-pick for version 0.64.3. Hopefully, it will be included.

Oh very cool! Thanks!

In that case, duplicate of #31193 🙂
