false, true and null case collision with phpcs

phpcs using Drupal coding standards require for FALSE, TRUE and NULL to be uppercase but prettier formats them to lowercase.
phpcs error message: TRUE, FALSE and NULL must be uppercase; expected "FALSE" but found "false"

prettier@2.0.5

prettier/plugin-php@0.14.3

Input:

  $vars = [
    'account' => $account,
    'manage_access' => FALSE,
  ];

Output:

  $vars = [
    'account' => $account,
    'manage_access' => false,
  ];

Expected behavior:

  $vars = [
    'account' => $account,
    'manage_access' => FALSE,
  ];

Prettier output:

Riproduci il problema con l’input PHP fornito usando prettier@2.0.5 e prettier/plugin-php@0.14.3, quindi esamina il percorso del formatter che gestisce FALSE, TRUE e NULL. Il lavoro è completato quando la formattazione conserva i literal in maiuscolo richiesti dai Drupal coding standards senza produrre l’errore phpcs segnalato.
