Module names containing numbers trigger false positive in type check

Hey,

all our custom modules are prefixed by "aw24_". This results in namespaces similar to this:

/**
   * Set the ID of the assigned user entity.
   *
   * @param int $uid
   *   User ID to set.
   *
   * @return \Drupal\aw24_user\Entity\UserInterface
   *   The User ID.
   */
  public function setOwnerId($uid);

which in turn phpcs marks as error, suggesting instead:

Expected "\Drupal\aw_user\Entity\UserInterface" but found "\Drupal\aw24_user\Entity\UserInterface" for function return type

Drupal coding standards do forbid module names beginning with numbers, but not containing them.

I can prevent this error by altering FunctionCommentSniff.php::suggestType and adding "0-9" to the RegExp below

    public static function suggestType($type)
    {
        if (isset(static::$invalidTypes[$type]) === true) {
            return static::$invalidTypes[$type];
        }

        if ($type === '$this') {
            return $type;
        }

        $type = preg_replace('/[^a-zA-Z0-9_\\\[\]]/', '', $type);

        return $type;

    }

This would allow types beginning with / consisting solely of numbers though.
