Some "missing peer" errors occurs when using pnpm install.

peerDepenendencies should be raised to storybook 7 to fix the errors.

Unfortunately the range ^6.4.0 || ^7.0.0 does not include the prerelease versions.
I would have thought we should use ^6.4.0 || >=7.0.0-beta <7.0.0 || ^7.0.0, but it seems that might not work either according the the calculator: https://semver.npmjs.com/
Maybe we could exclude v6 and use >=7.0.0-beta <7.0.0 || ^7.0.0?

No plan to support unstable releases. Use dependency resolutions if you want suppress warnings.
