Remove the following limitation when restoring a sharded collection using selective restore:

Selective restore of sharded collections from either a full logical backup or a selective logical backup is not supported if the distribution of chunks in the backup differs from the distribution of chunks in the existing collection. The supported way to restore in this scenario is to drop the target collection before performing the selective restore, ensuring shard metadata is recreated consistently.
