* kubelet-in-userns.md: fix unexpected config paths
Referring to `/etc/containerd/config.toml` makes sense only when the user has
read/write permissions to `/etc/containerd/config.toml` in the current mount
namespace, which is not always assumed in the context of this documentation.
The same applies to `/etc/crio/crio.conf`, too.
Partially revert PR 30020.

* kubelet-in-userns.md: add back the link to example port forwarder implementation
Add back the link to `k3s/pkg/rootlessports/controller.go` removed in PR 30020.
As stated in `{{ <note> }}`, the corresponding section is written for developers
of Kubernetes distros, not for end users.
So we should retain the implementation details here.
Partially revert PR 30020.
