Profile picture download from Instagram

Describe the bug

The download of profile pictures from Instagram is not working for my setup.
While testing the code locally, I discovered that the Instagram page does not fit to the code and has probably changed. But the link to the profile picture is still present on the page.
The easiest way to get it is the regex: /"profile_pic_url":\s?"(.*)",/U
With that I was able to extract the URL and get the image.

Steps to reproduce

Download page

$url = "https://www.instagram.com/{username}/\?__a\=1";
$options = array('http' => array('user_agent' => 'Googlebot / 2.1'));
$context = stream_context_create($options);
$result = file_get_contents($url,false, $context);

extract URL with preg_match
Check URL in browser

Expected behavior

The profile picture gets extracted.

Actual behavior

The profile picture is not extracted.
