Out-of-the-Box Errors with provided Next.js 15 example

**Describe the bug**
The Next.js 15 example does not work out of the box and uses a version of Next.js with a security vulnerability [CVE-2025-29927](https://github.com/vercel/next.js/security/advisories/GHSA-f82v-jwr5-mffw). When you try to install dependencies, there are dependency conflicts that you need to resolve manually. Even once you update the dependencies, you still receive a console error that something isn't working as it should (even though a PDF is generated).

While most can probably make their way through this or copy the error into ChatGPT to see what's going on, it just looks better for the project if the provided examples work well out of the box.

**To Reproduce**
Steps to reproduce the behavior including code snippet (if applies):

1. Clone @react-pdf/renderer repo.
2. Navigate to packages>examples>next-15
3. Install dependencies (I use npm, `npm install`)
4. See error.

**Expected behavior**
I should be able to install and view the example without errors.

**Screenshots**
_No change to package.json_

_Update React dependencies, but not Next.js_

_PDFViewer error_
