Missing / Incorrect Definition

JSON.rawJSON() appears to be missing. Apologies if I've missed something or if this is the wrong place to raise an issue. I searched through both PRs and issues in both this repo and https://github.com/microsoft/TypeScript-DOM-lib-generator but couldn't find any references for it.

Sample Code

const x = JSON.rawJSON('0')

MDN also documents this feature here.

Additionally, it appears to have been implemented in V8 and in webkit.

Testing experimentally, it is available in node 22+ and in the latest Chromium as well:
