Cannot install this module on Drupal 9: InfoParserException, undo semi-support for Drupal 9 for now

I get this exception when I try to install the upgrade status module on a new Drupal 9 installation. I simply downloaded the module with composer

composer require 'drupal/upgrade_status:^2.0'

and when I visit /admin/modules or I try to activate via drush drush en upgrade_status I get this exception.

Drupal\Core\Extension\InfoParserException: The 'core_version_requirement' constraint (9.0.2) requires the 'core' key not be set in modules/contrib/upgrade_status/tests/modules/upgrade_status_test_contrib_error/upgrade_status_test_contrib_error.info.yml in Drupal\Core\Extension\InfoParserDynamic->parse() (line 88 of core\lib\Drupal\Core\Extension\InfoParserDynamic.php).

configure: upgrade_status.report
