gitlab-kas does not run in dsop release smoke test
As seen in the release 18.10.0 gitlab-kas does not come up when doing a smoke test via docker compose up -d
Logs show
```
kas-1 | {"time":"2026-03-19T22:55:34.006498834Z","level":"ERROR","msg":"Program aborted","error":"kubernetes_api: read file: open : no such file or directory"}
```
It looks like some configuration/file/env var is missing.
It should be investigated and potentially fixed. There are no indications that the release was not OK but this is an anomaly and we should understand why it happens.
