Improvement of Meeting Room Capacity Management

Currently, the maximum capacity is hardcoded in the system with a value of 10. This value should be part of the content type to allow modification per room.

    $max_capacity = 10;
    $options = [];
    for ($o = 1; $o <= $max_capacity; $o++) {
      $options[$o] = $o . " " . $this->t("Capacity");
    }

    $form['capacity'] = [
      '#type' => 'select',
      '#title' => $this->t('Capacity'),
      '#options' => $options,
      '#default_value' => 1,
      '#required' => TRUE,
    ];
