Issue

According to the ECMAScript specification, ThrowStatement is required to have an expression as argument:

https://tc39.es/ecma262/#sec-throw-statement

But in ast-spec, the argument is exposed as a statement or null:

https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/ast-spec/src/statement/ThrowStatement/spec.ts

import type { AST_NODE_TYPES } from '../../ast-node-types';
import type { BaseNode } from '../../base/BaseNode';
import type { TSAsExpression } from '../../expression/TSAsExpression/spec';
import type { Statement } from '../../unions/Statement';

export interface ThrowStatement extends BaseNode {
  type: AST_NODE_TYPES.ThrowStatement;
  argument: Statement | TSAsExpression | null;
}
