Replace deprecated node_type_get_names() calls with entity_type.bundle.info service

Problem/Motivation

PHPStan reports deprecation errors due to the use of the deprecated node_type_get_names() function.
This function is deprecated in Drupal 11.3.0 and removed in Drupal 13.0.0.
The recommended replacement is \Drupal::service('entity_type.bundle.info')->getBundleLabels('node').

Note: Using configuration file /builds/project/calendar/web/modules/custom/calendar/phpstan.neon.

Proposed resolution

Replace calls to node_type_get_names() with calls to the entity type bundle info service:
\Drupal::service('entity_type.bundle.info')->getBundleLabels('node').
