Merge #1698

1698: Add `"packageManager"` entry to package.json r=brunoocasali a=flevi29

# Pull Request

## Why?
- [`corepack`](https://nodejs.org/docs/latest-v20.x/api/corepack.html) [started adding this field automatically](nodejs/corepack#413), which can be disabled, but everyone has to do it separately, which is very annoying
- anyhow there's no harm in it, `corepack` recommends it even in the "how to disable" doc https://github.com/nodejs/corepack/blob/main/README.md#environment-variables
  - > it ensures that your project installs are always deterministic (if you use `corepack`)
- this does mean that this field will have to be updated periodically, but this is the recommended way
