Steps to reproduce

1. Get a local git clone of Drupal core 11.x.
2. composer require drupal/config_inspector— or manually install https://www.drupal.org/project/config_inspector/releases/2.1.5 or newer (which supports Drupal 11!)
3. composer require drush/drush
4. vendor/bin/drush config:inspect --filter-keys=core.menu.static_menu_link_overrides --detail --list-constraints

Proposed resolution

Add validation constraints to:

1. definitions
2. menu_name
3. parent

For examples, search *.schema.yml files for the string constraints:😊
