Http chaining doesn't work correctly with native Illuminate client

Hi there!

Thanks so much for the great package. I'm running into a weird issue on 0.2 when chaining rate limiting and retry strategy, or anything else.

Take for example, this code:

return Http::withRetryStrategy($strategy, [
            'max_attempts' => 5,
            'base_delay' => 2.5,  // Configures the baseDelay parameter of the underlying strategy
            'timeout' => 15,
        ])->withHeaders($headers)

It works fine and the retry strategy is correctly implemented.

However, when I try this --

return Http::withHeaders($headers)->withRetryStrategy($strategy, [
            'max_attempts' => 5,
            'base_delay' => 2.5,  // Configures the baseDelay parameter of the underlying strategy
            'timeout' => 15,
        ]);

I get the following:

  Method Illuminate\Http\Client\PendingRequest::withRetryStrategy does not exist.

  at vendor/laravel/framework/src/Illuminate/Macroable/Traits/Macroable.php:112
    108▕      */
    109▕     public function __call($method, $parameters)
    110▕     {
    111▕         if (! static::hasMacro($method)) {
  ➜ 112▕             throw new BadMethodCallException(sprintf(
    113▕                 'Method %s::%s does not exist.', static::class, $method
    114▕             ));
    115▕         }
    116▕```

Interestingly, I have the same problem when I try to chain `withRetryStrategy` combined with `withRateLimitHandling`

    return Http::withRetryStrategy($strategy, [
        'max_attempts' => 5,
        'base_delay' => 2.5,  // Configures the baseDelay parameter of the underlying strategy
        'timeout' => 15,
    ])->withRateLimitHandling()->withHeaders($headers);

This code also fails with BadMethodCall to withRateLimitHandling. I'm fairly new to php and Laravel, working on a Laravel 10 app, so please let me know if I'm doing something idiotic here, but I did confirm that other method chaining works fine --

return Http::withHeaders($headers)->withUserAgent('1234');

PHP 8.1, Laravel 10

Thanks!
