Drupal\Core\Render\Renderer::render with $is_root_call is deprecated in drupal:11.2.0

Problem/Motivation

As of Drupal 11.2.0, using \Drupal\Core\Render\Renderer::render() with the second argument $is_root_call is deprecated and will be removed in Drupal 12.0.0.

The current implementation in GeofieldGoogleMapViewStyle::render() calls:

$rendered = $this->renderer->render($build, TRUE);

This triggers a deprecation warning:

Drupal\Core\Render\Renderer::render with $is_root_call is deprecated in drupal:11.2.0 and is removed from drupal:12.0.0. Use Drupal\Core\Render\Renderer::renderRoot() instead.

This causes noisy logs in test output and will break functionality in Drupal 12.

Steps to reproduce

1. Install the geofield_map module on a Drupal 11.2+ site.
2. Create a View using the Geofield Google Map view style.
3. Trigger a render of the View display (e.g. by visiting the page or running automated tests).
4. Observe PHP deprecation notices for the use of Renderer::render() with the $is_root_call parameter.

Proposed resolution

Replace the deprecated call to Renderer::render() with Renderer::renderRoot() when rendering the $build array.

Suggested code change:

- $rendered = $this->renderer->render($build, TRUE);
+ $rendered = $this->renderer->renderRoot($build);

This eliminates the deprecation and aligns with the forward-compatible API.

Remaining tasks

3. Get maintainer review.
4. Commit patch.
