Create registration permission does not exist

Problem/Motivation

RegistrationAccessControlHandler refers to a global 'create registration' permission that does not exist:

  protected function checkCreateAccess(AccountInterface $account, array $context, $entity_bundle = NULL): AccessResultReasonInterface|AccessResult|AccessResultInterface {
    $result = parent::checkCreateAccess($account, $context, $entity_bundle);
    if ($result->isNeutral()) {
      $permissions = [
        $this->entityType->getAdminPermission() ?: 'administer registration',
        'create registration',
      ];

Proposed resolution

Remove that reference.

Add the permission.
