Subject: [PATCH] fix(types): make parseReviver context.source optional per
 ES2023 spec (#10837)

Per the TC39 proposal-json-parse-with-source, context.source is only
set when the reviver is invoked on a primitive value (string, number,
boolean, null). For object/array values, source is absent from the
context object.

Changed context?: { source: string } to context?: { source?: string }
in both index.d.ts and index.d.cts.

Fixes #10817
