readline: remove question method from InterfaceConstructor

That method is overwritten in both
`require('node:readline').Interface.prototype` and
`require('node:readline/promises').Interface.prototype`, and is very
much not useful outside of interacting with TTY, removing it from the
parent class could enable the use of `InterfaceConstructor` in other
contexts (such as interacting with files).

 If the `InterfaceConstructor` was created with `output` set to `null` or
 `undefined` the prompt is not written.
 
-### `rl.question(query[, options], callback)`
-
-<!-- YAML
-added: v0.3.3
--->
-
-* `query` {string} A statement or query to write to `output`, prepended to the
-  prompt.
-* `options` {Object}
-  * `signal` {AbortSignal} Optionally allows the `question()` to be canceled
-    using an `AbortController`.
-* `callback` {Function} A callback function that is invoked with the user's
-  input in response to the `query`.
-
-The `rl.question()` method displays the `query` by writing it to the `output`,
-waits for user input to be provided on `input`, then invokes the `callback`
-function passing the provided input as the first argument.
-
-When called, `rl.question()` will resume the `input` stream if it has been
-paused.
-
-If the `InterfaceConstructor` was created with `output` set to `null` or
-`undefined` the `query` is not written.
-
-The `callback` function passed to `rl.question()` does not follow the typical
-pattern of accepting an `Error` object or `null` as the first argument.
-The `callback` is called with the provided answer as the only argument.
-
-An error will be thrown if calling `rl.question()` after `rl.close()`.
-
-Example usage:
-
-```js
-rl.question('What is your favorite food? ', (answer) => {
-  console.log(`Oh, so your favorite food is ${answer}`);
-});
-```
-
-Using an `AbortController` to cancel a question.
-
-```js
-const ac = new AbortController();
-const signal = ac.signal;
-
-rl.question('What is your favorite food? ', { signal }, (answer) => {
-  console.log(`Oh, so your favorite food is ${answer}`);
-});
-
-signal.addEventListener('abort', () => {
-  console.log('The food question timed out');
-}, { once: true });
-
-setTimeout(() => ac.abort(), 10000);
-```
