This doesn't seem to be a complete fix, I'm still getting "docker CLI not found on $PATH" on the test build:

... ERROR [dev_container::devcontainer_api] Unable to find docker in $PATH: Os { code: 2, kind: NotFound, message: "No such file or directory" }
... ERROR [recent_projects::remote_servers] Failed to start dev container: DockerNotAvailable

You only need --filesystem=xdg-run/docker and --filesystem=xdg-run/podman for this to work.
