Check 10.3 version from 10.2 version

Need to check the 10.3 version

My site is running on Drupal 10.2. I need to update the core to 10.3 (for the moment). I installed this module to test compatibility with Drupal 10.3. However, in the status page, the check is done with version 10.4. How to choose the destination version (10.3 for me) ?

Thanks for your help.
