Move storybook packages to peer deps

[IanVS]

I had a test failure begin in storybookjs/builder-vite#357 when updating the test-runner to anything higher than 0.0.5-next.0. I traced it down to the test-runner installing and using a 6.4 version of @storybook/store, while my storybook project is on 6.5.0-beta.0.

I think this change is the correct way to handle this, by moving the storybook projects to peerDependencies, with a range that includes 6.5.0 pre-releases. Any other approach risks installing a different version for the test runner than what is installed in the main project.

Using this canary, I get yarn warnings like

YN0002: │ example-react@workspace:examples/react doesn't provide @storybook/store (p38ca6), requested by @storybook/test-runner

in my project, but it's no longer breaking the tests. It seems like yarn peer dependencies don't consider transitive deps. Or maybe it's a workspaces issue.
