[question] Any plans to move or support vitest?

[AmirTugi]

test-runner is currently running using jest, and the rest or the ecosystem of storybook is already running on vitest
See for example the @storybook/test package.

I believe that vitest would benefit a lot to speed up the testing.
I'm using this package for the a11y testing, and currently this is by far the slowest operation in my CI (I admit that I have a lot of stories, and I still think we could benefit from vitest).
