Describe the bug

Setting a value in an array using an index doesn't trigger a violation of the rule 0012.

To Reproduce Steps to reproduce the behavior:

• Create a simple service class, like this:

  
  <?php
  namespace App\Service;
  class CacheService
  {
  private array $cache = [];
  
  public function __construct()
  {
      $this->cache = [];
  }
  
  public function arraySet(int $value): int{
      if(isset($this->cache[$value])){
          return $this->cache[$value];
      }
      $this->cache[$value] = $value * 2 + 1;
      return $this->cache[$value];
  }
  }

- Launch phanalist on it
- No violation

**Expected behavior**
Setting a value in an array should trigger a violation of the 0012 rule.
