When are debian testing packages merged to PureOS 10 repo?

Is there a way to get newer versions with APT?

Perhaps (didn’t test this by myself), not sure. And easier to control if these two CLI commands executed individually:
sudo apt install krita
sudo apt install podman

Please take a look here (quite similar procedure):

@Quarnero

Add: deb https://ftp.debian.org/debian/ bookworm main
sudo apt update
sudo apt install gcc-11-base locales libc-bin libc6 libstdc++6 libetonyek-0.1-1
Block/remove: bookworm main from your sources.list
sudo apt update
