Older version nodes are listed as Decommissioned in the UI after upgrading the cluster to v22.2.16

**Describe the problem**

Older version nodes are listed as Decommissioned in the UI after upgrading the cluster to v22.2.16

**To Reproduce**

What did you do? Describe in your own words.

If possible, provide steps to reproduce the behavior:

1. Set up CockroachDB cluster of version v20.x
2. Decommission set of nodes
3. Upgrade the cluster to v22.x or latest
4. Check the Overview Page and the older decommissioned nodes should be appear in the page.

**Expected behavior**
The Overview Page should not list older decommissioned nodes.

**Additional data / screenshots**
The decommissioned nodes should not be listed in the UI:
For ex:

But in the customer environment we see that the decommissioned node(s) still showing up in the dashboard, refer the screenshots from our internal issue: https://github.com/cockroachlabs/support/issues/2740

The symptoms of this issue matches the one symptom `Overview Page lists the older Decomissioned nodes` in github issue#https://github.com/cockroachlabs/support/issues/2644 but we do not see any `MIXED VERSIONs`.

**Environment:**
- CockroachDB version v22.2.16
- Server OS: Linux
- Cluster config: 65 Nodes with below config:

```
"total_system_memory": 129275179008,
"num_cpus": 32
```
