We currently allow applications to configure checkpoint cleanup to run between 60s and 100000s while th default value is 300s. This was done as part of WT-12657.

We should look into at least updating the lower bound. Lots of our tests don't run for more than 60s so setting to the current lowest bound still does not let us test the functionality.

Note: The component is checkpoint but that's misleading from 8.0 since checkpoint cleanup is no longer part of checkpoint.
