`coder templates version list` makes a call to determine the `active`
version:
```
➜ ~ coder templates version list aws-linux-dynamic
NAME CREATED AT CREATED BY STATUS ACTIVE
infallible_feistel2 2025-10-10T10:34:02+11:00 rowansmith Succeeded Active
mystifying_almeida1 2025-10-10T10:32:38+11:00 rowansmith Succeeded
```
but this is not carried across to the `-ojson` output version, so this
PR implements that in order to support programattic addressing.
It is added a top level entry. If it should be nested under
`TemplateVersion` let me know.
```
➜ ~ ./Downloads/coder-cli-templateversions-json-active templates version list aws-linux-dynamic -ojson | jq '.[] | select(.active == true) | { active, id: .TemplateVersion.id }'
{
"active": true,
"id": "38f66eae-ec63-49b7-a9d2-cdb79c379d19"
