You are right that the individual loopbacks are /24 networks, but the task 3 specifically says R6 is receiving a summary address for both loopbacks of R2. The summary for 192.168.2.0/24 and 192.168.3.0/24 is 192.168.2.0/23.
So the prefix-list entry permit 192.168.2.0/23 is correct because the ISP is advertising that summary route. It does not mean the physical loopback interfaces are configured as /23, it means the BGP route being matched is the summarized prefix.
