[BUG] Exporting data from the existing replicas has issues in 1.6.0

[manju-rn]

Describe the bug

As per this documentation https://longhorn.io/docs/1.6.0/advanced-resources/data-recovery/export-from-replica/ Data from the replicas can be extracted and loaded as a device. However, in the latest documentation of 1.6.0, during the execution of Step 5, it results in error, with longhornio/longhorn-engine:v1.6.0

Error:
longhorn-instance-manager: error while loading shared libraries: libqcow.so.1: cannot open shared object file: No such file or directory

Resolution (Temporary)
However, by using longhornio/longhorn-engine:v1.5.4, it works fine. So believe some libs are missing in longhornio/longhorn-engine:v1.6.0

To Reproduce

Follow section 5 in https://longhorn.io/docs/1.6.0/advanced-resources/data-recovery/export-from-replica/ to extract the data from the replicas.

Further details are in #8092
