Add a sub-module for supporting alt text generation from OpenAI

Added a sub-module, currently only works with the media gallery image upload.

The prompt should be translatable in order to support multilingual.

Hi,

I suggest using another AI tool, ALTTEXTAI, to generate image alternative text. Additionally, we have a Drupal module called Automatic Alternative Text that supports generating ALT text for uploaded media files.

Example Code:

    $data = array(
		'image' => array(
			'url' => 'https://upload.wikimedia.org/wikipedia/commons/6/63/Monarch_In_May.jpg'
		),
	);
	$json_data = json_encode($data);

	$Curl = 'https://alttext.ai/api/v1/images';
	$access = '146971ebfd0cf123d9126f1e9e89f065';
	$ch1 = curl_init();
	curl_setopt($ch1, CURLOPT_URL,$Curl);
	curl_setopt($ch1, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'X-API-Key: '.$access));
	curl_setopt($ch1, CURLOPT_RETURNTRANSFER, true);
	curl_setopt($ch1, CURLOPT_CUSTOMREQUEST,"POST");
	curl_setopt($ch1, CURLOPT_POSTFIELDS, $json_data);
	
	$status_code = curl_getinfo($ch1, CURLINFO_HTTP_CODE); 
	$result = curl_exec($ch1);
	curl_close($ch1);
	$response = json_decode($result, true);

	$response1 = array(
		"alt_text" => $response['alt_text'],
		"img_url" => $url,
	);
	echo json_encode($response1);

Just reporting back here that there's also the AI Image Alt Text module → option for the AI suite of modules → .

I added some changes to the MR to make it work with media edit and support the DropzoneJS module.
