Config schema error after 1.1.2 update

Problem/Motivation

Something seems not right with the config schema which was introduced in ✨ Configuration interface Active .

The Config Inspector module also confirms the same issue.

>  [notice] Update started: markdownify_update_10003
>  [warning] Schema errors for markdownify.settings with the following errors: markdownify.settings:supported_entities.node missing schema, markdownify.settings:supported_entities.taxonomy_term missing schema. These errors mean there is configuration that does not comply with its schema. This is not a fatal error, but it is recommended to fix these issues. For more information on configuration schemas, check out <a href="https://www.drupal.org/docs/drupal-apis/configuration-api/configuration-schemametadata">the documentation</a>.
>  [notice] Added default "supported_entities" configuration for supported entity types: node, taxonomy_term.
>  [notice] Update completed: markdownify_update_10003
