The `--force` flag for `k8s remove-node` did not work for lost nodes because it required a node to be available to remove it. This commit ensures that all mentions of the leaving node will be removed (etcd, microcluster, k8s-dqlite, Kubernetes) and not fail if the node does not exist already in one of them.
* Adds a section to the troubleshooting page * Updates the warning in the uninstall tutorial

Backport of #1886 without 6b958c3 because this test does not exist in 1.32. We could consider backporting this along with #1773
