Node 14 Circular dependency error due to ShellJS

[clementprevot]

This is a reopening of #11173

Describe the bug

When running Storybook with Node 14, there are a lot of "Circular dependencies" error thrown (that doesn't affect the proper working of Storybook though):

When running with --trace-warning here is the result:

So clearly the issue is coming from ShellJS.
And indeed, there are some issues over there talking about that.

And the solution is simple: update to ShellJS 0.8.4.

AFAIK, @storybook/root is using 0.8.4, but not @storybook/core.

The last message of the previous issue suggested to create a PR to upgrade the package but I think that nobody did it.

So I'm reopening this issue and will issue a PR to solve it.

Son of a gun!! I just released https://github.com/storybookjs/storybook/releases/tag/v6.1.0-alpha.26 containing PR #12794 that references this issue. Upgrade today to the @next NPM tag to try it out!

npx sb upgrade --prerelease

Closing this issue. Please re-open if you think there's still more to do.
