Write more tests for verifying the developer experience using listener types in TypeScript

Description

We can have tests verifying all explicit types of listeners are available in TypeScript. For instance, for view_submission handling, the following code would be the case. I haven't checked all others yet but having TS tests like this helps us detect breaking changes and also share examples when answering questions.

import { App, Middleware, SlackViewMiddlewareArgs, ViewSubmitAction } from '@slack/bolt';
const app = new App({
  token: process.env.SLACK_BOT_TOKEN,
  signingSecret: process.env.SLACK_SIGNING_SECRET
});
const modalListener: Middleware<SlackViewMiddlewareArgs<ViewSubmitAction>> = async ({ ack }) => {
  await ack();
};
app.view("modal", modalListener);

Requirements (place an x in each of the [ ])

• I've read and understood the Contributing guidelines and have done my best effort to follow them.
• I've read and agree to the Code of Conduct.
• I've searched for any related issues and avoided creating a duplicate issue.

Start by locating the TypeScript listener type definitions and the app.view entry point. Add compile-time test cases for the shown SlackViewMiddlewareArgs example and the other explicit listener types, then confirm the tests compile without breaking changes.
