Support for Firefox headless

[thbley]

It would be nice if Firefox would be supported as well.
(my initial tests with MS Edge 120 on Linux were successful without further patches)

From "https://firefox-source-docs.mozilla.org/remote/index.html#remote-protocol-cdp-header":
Firefox implements a subset of the Chrome DevTools Protocol (CDP) in order to support third party automation tools such as puppeteer.

E.g. I patched the handshake:

GET /devtools/browser/ef8d2af9-3280-42f0-b812-c49b8dbaca19 HTTP/1.1
host: 127.0.0.1:9222
upgrade: websocket
connection: Upgrade
sec-websocket-key: 4InfZD3P8p82pb4iQ1wLKQ==
origin: http://127.0.0.1
sec-websocket-version: 13

HTTP/1.1 400 Bad Request
Server: httpd.js
Content-Type: text/plain
Content-Length: 66

with:

   protected function getDefaultRequestHeaders(
       string $host,
       string $key,
       string $origin
   ): array {
       return [
           self::HEADER_HOST => $host,
           self::HEADER_UPGRADE => self::UPGRADE_VALUE,
           self::HEADER_CONNECTION => self::CONNECTION_VALUE,
           self::HEADER_KEY => $key,
           // self::HEADER_ORIGIN => $origin,
           self::HEADER_VERSION => (string) $this->getVersion(),
       ];
   }

I also patched Frame::__construct:

TypeError: HeadlessChromium\Frame::getLatestLoaderId(): Return value must be of type string, null returned
  │
  │ /home/tb/code/php_frameworkless/tasks_be/tests/vendor/chrome-php/chrome/src/Frame.php:98
  │ /home/tb/code/php_frameworkless/tasks_be/tests/vendor/chrome-php/chrome/src/PageUtils/PageNavigation.php:84
  │ /home/tb/code/php_frameworkless/tasks_be/tests/vendor/chrome-php/chrome/src/Page.php:216

with:

   public function __construct(array $frameData)
   {
       $this->frameData = $frameData;
       $this->latestLoaderId = $frameData['loaderId'] ?? 0;
       $this->frameId = $frameData['id'];
   }

Versions:
Firefox 121.0
chrome-php/chrome v1.10.0

Headless Firefox also requires to change 2 preferences to work with ChromeDP: https://firefox-source-docs.mozilla.org/remote/cdp/RequiredPreferences.html

Reference for startup parameters and setting initial preferences from puppeteer:
