use of experimental node features causes warnings

[aspiers]

Describe the bug

If I run pnpm dev on a fresh install, I see these two warnings:

(node:22422) ExperimentalWarning: Import assertions are not a stable feature of the JavaScript language. Avoid relying on their current behavior and syntax as those might change in a future version of Node.js.
(Use `node --trace-warnings ...` to show where the warning was created)
 Manifest file copy complete: /home/adam/git/chrome-extension-boilerplate-react-vite/dist/manifest.json
built in 1260ms.
(node:22422) ExperimentalWarning: Importing JSON modules is an experimental feature and might change at any time

I believe these are caused by the following import:

chrome-extension-boilerplate-react-vite/manifest.js

Line 1 in 6b61cd1

import packageJson from './package.json' assert { type: 'json' };

To Reproduce
Steps to reproduce the behavior:

1. git clone https://github.com/Jonghakseo/chrome-extension-boilerplate-react-vite.git
2. cd chrome-extension-boilerplate-react-vite
3. pnpm i
4. pnpm dev

Expected behavior
It should start up with a clean output with no warnings.

I see that node recently gained a --disable-warning option, so this might be a good solution, although ideally we could just avoid using experimental features altogether. Is there another way to get manifest.js to read package.json at compile time?
