Reproduction

Repo: https://github.com/nuxt/framework

Describe the bug

setupTimeout seems to do nothing, checking the codebase of this repo I cannot find setupTimeout or setupTest anywhere besides in the docs + the options object:

• setupTimeout: https://github.com/nuxt/framework/search?q=setupTimeout&type=code
• setupTest: https://github.com/nuxt/framework/search?q=setupTest&type=code

Additional context

Testing using the test-utils takes quite long right now - 30 - 60 seconds of setup time. I wanted to reduce this and one guess of mine was that the setupTimeout can help with that. Upon further investigation I could not find it doing anything.

Let me know if this is actually a flaw, I'd be open to remove this part from the docs or extend code to apply setupTimeout.
