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

// https://www.typescriptlang.org/play/?target=99#code/MYewdgzgLgBAHjAvDAUgZQPIDkB0AnAQwHd1sAKAcgAYKBKIA
const x = JSON.rawJSON('0')

Documentation Link

Per https://github.com/microsoft/TypeScript/issues/19044 it seems like TypeScript's policy is to support Stage 3+ features and proposal-json-parse-with-source is stage 3. (If I misunderstood the typescript teams policy on experimental features it would be awesome to have this documented in https://github.com/Microsoft/TypeScript/wiki/FAQ)

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:

Start by reviewing the ESNext library definitions and comparing their JSON APIs with the proposal-json-parse-with-source specification. Use the TypeScript sample in the issue to check the missing declarations, including JSON.rawJSON(), JSON.isRawJSON(), and the reviver context parameter, then verify the ESNext target accepts them.
