Describe the Bug

There was another NullReferenceException in this file(packages/next/client/head-manager.ts) that has been resolved before. The related issue and the PR are below.

Issue: #30604
PR: #30919

I did not understand the point of using exclamation marks for the possible Null Reference Exceptions instead of question marks as a shorthand?

I will refactor the file again that the file name has been provided in the issue title, and will open another PR.
Or, maybe the Next.js team can be considered to refactor the related file from scratch as well.

Thanks in advance.

Expected Behavior

Should work like a charm.

To Reproduce

Using next/head within any of the components and deploying the app with next export.

import Head from 'next/head';
