chore: pin TSDoc related dependencies (#6063)
Without the API-* dependencies pinned different versions may be
installed on local machines vs CI. One of the checks we do is to check
that the checked in docs matches what is generated on CI. Therefore we
need to ensure devs locally run the exact version that CI runs such that
they generate the same output. So in this case we pin to a particular
version of the dependencies.

## Page class
Page provides methods to interact with a single tab or \[extension background page\](https://developer.chrome.com/extensions/background\_pages) in Chromium. One \[Browser\] instance might have multiple \[Page\] instances.
<b>Signature:</b>
```typescript
export declare class Page extends EventEmitter
```
<b>Extends:</b> [EventEmitter](./puppeteer.eventemitter.md)
## Remarks
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Page` class.
## Example 1
This example creates a page, navigates it to a URL, and then \* saves a screenshot:
```js
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://example.com');
await page.screenshot({path: 'screenshot.png'});
await browser.close();
})();
```
The Page class extends from Puppeteer's [EventEmitter](./puppeteer.eventemitter.md) class and will emit various events which are documented in the [PageEmittedEvents](./puppeteer.pageemittedevents.md) enum.
## Example 2
This example logs a message for a single page `load` event:
```js
page.once('load', () => console.log('Page loaded!'));
```
To unsubscribe from events use the `off` method:
```js
function logRequest(interceptedRequest) {
console.log('A request was made:', interceptedRequest.url());
}
page.on('request', logRequest);
// Sometime later...
page.off('request', logRequest);
```
