Fix yarn.lock up to date with package.json

[simison]

#14056 introduced some unrelated yarn.lock changes.

Running yarn in master would always remove these from the lockfile.

Changes proposed in this Pull Request:

• Sync yarn.lock

Is this a new feature or does it add/remove features to an existing part of Jetpack?

• If you're an Automattician, include a shortlink to the p2 discussion with Jetpack Product here.

Testing instructions:

• Running yarn won't do any changes to lockfile like it does in master
