Only restore Yarn caches on exact key hits (#26133)

## Summary [Current Yarn cache size: 555MB](https://app.circleci.com/pipelines/github/facebook/react/38163/workflows/70d0149e-b0bc-44e8-b8c9-e5c744cab89b/jobs/625334?invite=true#step-102-2) [Used Yarn cache size: 344MB](https://app.circleci.com/pipelines/github/facebook/react/38166/workflows/4825d444-1426-4321-b95b-c540e6cdc6d7/jobs/625354?invite=true#step-104-5) When we restore a global Yarn cache that's not specific to a lockfile entry (i.e. a fallback cache), we might restore packages that are no longer used. When we then run yarn install, we potentially add new packages to the cache. For example: 1. we bump a package version 2. lockfile changes 3. cache restore misses for exact key 4. cache restore hits a prefix (fallback) containing the older version, 5. yarn install adds the new version to the cache Yarn is not clearing the unused packages from the global cache. So when we then save the cache we now retain the old and new version of a package in the global cache even though the old version is no longer used. This means that the global cache grows indefinitely. Restoring the cache isn't free so CI install times will degrade over time. Either we 1. periodically prune the cache 2. just not restore anything unless we have an exact hit. The chosen tradeoff depends on the relation of commits changing deps to commits not changing deps. From my experience, we change deps rarely so I opted to only restore the cache on exact hits. ## How did you test this change? - run on `main` has 555MB of Yarn cache: https://app.circleci.com/pipelines/github/facebook/react/38163/workflows/70d0149e-b0bc-44e8-b8c9-e5c744cab89b/jobs/625334?invite=true#step-102-2 - run on this branch only has 334MB of Yarn cache: https://app.circleci.com/pipelines/github/facebook/react/38166/workflows/4825d444-1426-4321-b95b-c540e6cdc6d7/jobs/625354?invite=true#step-104-5 DiffTrain build for [c0b0b3a](c0b0b3a) [View git log for this commit](https://github.com/facebook/react/commits/c0b0b3a9f80fd57e882859afd95c2f08599442ba)
