Bug for 10.2.x

Problem/Motivation

When i upgraded to 10.2, and then there is an error

The "block" entity type did not specify a view_builder handler. (web/core/lib/Drupal/Core/Entity/EntityTypeManager.php line 259)

Steps to reproduce

install new module

Proposed resolution

replace blocache_entity_type_build to these function in blocache.module

function blocache_entity_type_alter(array &$entity_types) {
    // Change the view_builder handler of the block entity.
    $entity_types['block']->setViewBuilderClass('Drupal\blocache\BlocacheViewBuilder');
}
