The problem was that even though I had reverted to iptables-legacy in Debian, I still had iptables: "false" in my docker daemon.json. On removing that, docker can use its default iptables impl and work with Debian Bullseye. Now, my containers can access "the internet".
I realize that your post indicated to use iptables: false as a way to get debian wsl2 instances to work with docker. But that never worked for me for some reason.
I had the same issue with Ubuntu in WSL2. Removing iptables: "false" from the daemon.json and switching to iptables-legacy did the trick. No full reboot was necessary, running "wsl --shutdown" in powershell + reopening the ubuntu shell did the trick. Thanks!

The issue is more easily reproduced on my system by just running ping commands inside the latest alpine image:

Yeah, I have actually changed the instructions, removing the iptables:false, as using iptables-legacy seems like the right way to do it.
