wide-image class should not be added for user pictures

Problem/Motivation

User picture should not be an "hero/wide" image because it is no more aligned

Steps to reproduce

Display the profil of a user having a defined picture (or a default one)

Proposed resolution

Adapt olivero_preprocess_field as follow:

function olivero_preprocess_field(&$variables) {
  ...
  if (
    $variables['field_type'] == 'image' &&
    $variables['element']['#view_mode'] == 'full' &&
    !$variables["element"]["#is_multiple"] &&
    $variables['field_name'] !== 'user_picture' // Here is the change
  ) {
    $variables['attributes']['class'][] = 'wide-image';
  }
}
