[Bug] `beforeEach` is not run inside component context

[Jakeii]

Describe the bug

Updating reactive state or contexts doesn't work from the beforeEach function.

This would be useful for changing context mocks between stories in the same file.

Steps to reproduce the behavior

1. Create a story
2. attempt to update a $state rune inside beforeEach -> reactivtity won't work, attempting to use getContext/setContext will also throw an error

Expected behavior

That the beforeEach function is run inside the context of the Story component, I've noticed there's some code to do this for the play function, can it be done for beforeEach too? Doesn't seem possible from play either
