Lower per object queue age and length thresholds (#19851)

## Description 

The original limits on the object queue are set with 1s checkpoint
interval. Having the oldest transaction on an object queued for 1s is
almost tolerable. In hindsight it should be lower than the checkpoint
interval to ensure healthy system. Now checkpoint interval is targeting
0.2s - 0.25s, so lowering the limits further to 0.2s, to ensure smooth
checkpoint constructions.

## Test plan 

CI
PT
Reading `num_rejected_cert_during_overload` metric from validators.

## Release notes

Check each box that your changes affect. If none of the boxes relate to
your changes, release notes aren't required.

For each box you select, include information after the relevant heading
that describes the impact of your changes that a user might notice and
any actions they must take to implement updates.
