parser: object destructuring in ambient module/namespace

[DonIsaac]

This code should parse with no errors

• Oxc Playground
• TypeScript Playground

declare module "foo" {
    let {a: x, b: x1}: {a: number, b: number}; // valid b/c ambient context
}

declare namespace Bar {
    let {a: x, b: x1}: {a: number, b: number}; // valid b/c ambient context
}

But it errors with

Error: Missing initializer in destructuring declaration

---

It looks like Context::Ambient is not getting updated correctly, even though it should be in parse_ts_declaration_statement
