Node decommissioning has seen some changes recently, e.g. in cockroachdb/cockroach#56529, that should be reflected in the 21.1 documentation:

https://www.cockroachlabs.com/docs/dev/remove-nodes.html

A node's status entry is now removed when the decommissioning operation completes (unless something goes wrong, in which case the operation can be run again). This means that the node will not show up under "Recently Decommissioned Nodes", since there is no longer an entry to show there. This needs to be updated a few places in the document (just search for "recently decommissioned"). I suppose the mentioned "historical list of decommissioned nodes" no longer applies either.

We may want to make some changes to DB Console following this as well.
