[requirements] Please consider bumping docker to 5.0.2 in Xena u-c

Hello, Xena upper constraints currently contain docker 5.0.1, released on August 31. This version includes a critical issue [1] which was fixed by version 5.0.2 released the next day. Except for a docstring update this is the only change, according to git diff. Would it be possible to update Xena u-c to use docker 5.0.2? We currently have to work around it in Kayobe to avoid installing the buggy version [2]. Thanks, Pierre Riteau (priteau) [1] https://github.com/docker/docker-py/issues/2885 [2] https://review.opendev.org/c/openstack/kayobe/+/807345/9/ansible/kolla-targe...
