Unknown attribute "userns_mode"

[Igetin]

I have the following line in my compose file’s service configuration:

userns_mode: "keep-id"

When trying to convert the compose file, podlet outputs the following error:

Error: 
   0: File `compose-debugging.yaml` is not a valid compose file
   1: services.test: unknown attribute "userns_mode", extensions must start with 'x-' (see https://docs.docker.com/compose/compose-file/#extension) at line 3 column 5

This should be supported by Quadlet in container/Kube units, according to the documentation.

• userns_mode in the Docker Compose file version 3 reference
• userns_mode in the Compose Specification

This is a bug in docker-compose-types, I'll create an issue there.
