chore: Don't store revisions in package.json (#6109)
* chore: Don't store revisions in `package.json`

It's quite messy to have to require the `package.json` file in multiple
places purely to find out what revision of a given browser we want to
use. We can also achieve better type safety by placing it in an actual
source file.

This commit makes that change and also tidies up our reliance on
`package.json` within the source code generally; we now only use it to
find the location of the Puppeteer root such that we know where to
install downloaded browsers to.

To avoid using `package.json` to parse the name of the module, we also
now explicitly have an entry point for the Puppeteer module and the
Puppeter Core module. This will make it easier in the future to ship
less code as part of core (e.g. core never needs to download a browser,
so why ship that code?). Core can also then not have any revisions based
info contained in it.

The test install script has also been updated to ensure that
puppeteer-core can be installed correctly too.

Finally, the `install` script has been moved to TypeScript for nicer
typechecking and safety. The functionality of it has not changed.

## Puppeteer class
The main Puppeteer class Puppeteer module provides a method to launch a browser instance.
<b>Signature:</b>
```typescript
export declare class Puppeteer
```
## 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 `Puppeteer` class.
## Example
The following is a typical example of using Puppeteer to drive automation:
```js
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://www.google.com');
// other actions...
await browser.close();
})();
```
