Describe the bug
podman-compose resolves extends after gating services on profile, meaning that if a service extends another service gated out by a profile, you get a KeyError.
To Reproduce
services:
base:
profiles: [_base]
image: docker.io/library/busybox
app:
extends: base
profiles: [app]
command: echo helloCOMPOSE_PROFILES=app podman-compose up
Expected behavior
It runs.
Actual behavior
Fails with a KeyError.
