Bug: Body data from curlrequest become unreadable when endpoint return long data

[densoooo]

Describe the bug
Body data returned from calling API using curlrequest become unreadable when the returned data is long. I can get normal json data from calling the same API if I'm using native php curl function. When the returned data is short, curlrequest will return normal json.
Sample code using curlrequest :

` $client = \Config\Services::curlrequest();

    $data = array(
		"q" => "php"
	);

    $response  = $client->get('https://api.github.com/search/repositories', [ 'query' => $data ]);
    echo $response->getBody();

`
Sample code using php curl :

`$curl = curl_init();

    curl_setopt_array($curl, array(
        CURLOPT_URL => 'https://api.github.com/search/repositories?q=php',
        CURLOPT_USERAGENT => 'Mozilla/5.0 (Windows NT 6.2; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0',
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "GET",
    ));

    $response = curl_exec($curl);
    echo $response;`

When sending data using curlrequest the returned body become something like this :
�����[�#�u���+�~��E4��-bC�m�Ύb�{f�ýX��jtM7�������c#�6E��C�#,J�dY�D��LQaK�Z���'�\VO��>U�K^Nf%*�v� 2��3���dV� ���N�~���YΖ���h��.w������ ��hv9�D���"�W�e۟��8Zo^F��+���m4n��'�N�5�s{���Ɏ���I�8ݴs���u4����n�&|�ݧ������~��������o씍��(i1?��/>YM&��ٖ���"Z4'��E��nq;����2��}N�2��F�x5�1�4����I$�W�͇���}�/F%���������*|�~vrw���|

CodeIgniter 4 version
v4.0.3

Affected module(s)
\Config\Services::curlrequest();

Expected behavior, and steps to reproduce if appropriate
Expected to get json data even when API return long data

Context

• OS: Windows 10
• Web server: Apache 2.4.35
• PHP version : 7.4.5

Apparently the problem was caused by the curl on vendor\codeigniter4\framework\system\HTTP\CURLRequest.php having Accept-Encoding: gzip, deflate, br on the CURLOPT_HTTPHEADER. Removing Accept-Encoding from header or adding CURLOPT_ENCODING with empty value to $curl_options will solve the problem with long json data
