Update for PHP 8.4

[gmoigneu]

The bridge generates some deprecation warning on PHP8.4:

Deprecated: Platformsh\ConfigReader\Config::__construct(): Implicitly marking parameter $environmentVariables as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/vendor/platformsh/config-reader/src/Config.php on line 152

Deprecated: Platformsh\ConfigReader\Config::getUpstreamRoutes(): Implicitly marking parameter $appName as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/vendor/platformsh/config-reader/src/Config.php on line 340

We should review and update the code to avoid this.
