[skip-ci] Packit: Enable CentOS Stream 10 update job

Packit now has recently added support to enable downstream PR updates to
CentOS Stream packages.
Ref:
https://packit.dev/docs/configuration/upstream/propose_downstream#syncing-the-release-to-centos-stream

CentOS Stream support is still in its early stages but this change
should be safe to add to upstream packit config.

Whenever there's a new Podman release, the rpm maintainer would need to
run `packit propose-downstream` using the packit CLI (not github
comment) to actually create the downstream update PR.
