Fix Drupal\Core\Link could not be converted to string in VarbaseContentOverview->build() when the comment module is enable

Updated to the latest varbase 8.7.0 release. When loading the dashboard:

The website encountered an unexpected error. Please try again later.
Recoverable fatal error: Object of class Drupal\Core\Link could not be converted to string in Drupal\Core\Render\Markup::create() (line 36 of core/lib/Drupal/Component/Render/MarkupTrait.php).
Drupal\Core\Render\Markup::create(Object) (Line: 181)
Drupal\varbase_total_control\Plugin\Block\VarbaseContentOverview->build() (Line: 135)
Drupal\panels\Plugin\DisplayBuilder\StandardDisplayBuilder->buildRegions(Array, Array) (Line: 176)...

Traced it down to: 180 - 184

[
  'data' => Markup::create($link),
  'class' => ['type'],
],

Should be:

[
  'data' => $link->toString(),
  'class' => ['type'],
],

Patch to follow later today.
