pasta: UDP port range forwarding: hang in podman logs

[edsantiago]

Very infrequent. I can't tell if it's parallel-related or not:

The podman logs --follow blocks until the container terminates. It looks like the container is not terminating.

Hopefully the same as #24147, but I can't reproduce that with these tests.
