useSearchParams() should not need to be wrapped in a suspense boundary

Why this is a good first issue

The issue involves both documentation updates and potential behavioral changes in a core hook.

AI Summary

The issue reports that `useSearchParams()` requires a Suspense boundary despite documentation suggesting otherwise, and an experimental flag mentioned in docs no longer exists. It requires verifying current behavior and updating documentation, with potential changes to the hook's requirements.

To Reproduce

Write a page that calls useSearchParams from next/navigation
Make it a client component by adding "use client" at the top
run npm run build
observe error useSearchParams() should be wrapped in a suspense boundary at page "/test". Read more: https://nextjs.org/docs/messages/missing-suspense-with-csr-bailout

Current vs. Expected behavior

The documentation associated with this error is no longer accurate- the linked page suggests to disable the error by adding the experimental feature missingSuspenseWithCSRBailout to next.config.js. This option does not work, and will cause the build to error out saying that feature/flag doesn't exist.
I don't see why useSearchParams is any different WRT suspense than any other client function like useState. I don't need suspense for them, and I don't see why I should need suspense for useSearchParams
This is not a problem in development- it neither gives an error nor has incorrect behavior.
