Docs: confusing cacheTag & cacheLife requirements

[Jordaneisenburger]

What is the documentation issue?

The docs state that "To use cacheLife, enable the dynamicIO flag in your next.config.js file:" but when I use cacheTag() & cacheLife() without the experimental dynamicIO flag enabled I get no warnings in my console and the two functions work perfectly fine.

Is there any context that might help us understand?

I'm running on 15.4.0-canary.23 so it could be that the public docs are out of sync but after checking the docs in the latest canary branch it also states dynamicIO needs to be enabled. https://github.com/vercel/next.js/blob/canary/docs/01-app/05-api-reference/04-functions/cacheLife.mdx

Does the docs page already exist? Please link to it.
