incubator/valkey: replace remaining redis-cli probes with valkey-cli (#45014)

`incubator/valkey` still used Redis CLI references in probe scripts,
which made the chart inconsistent with Valkey naming. This update aligns
healthcheck command paths with Valkey while keeping existing runtime
compatibility env vars intact.

- **Probe command alignment**
- Updated all health probe scripts in
`charts/incubator/valkey/values.yaml` to call `valkey-cli` instead of
`redis-cli`:
    - `ping_readiness_local.sh`
    - `ping_liveness_local.sh`
    - `ping_readiness_master.sh`
    - `ping_liveness_master.sh`

- **Chart metadata**
  - Bumped `charts/incubator/valkey/Chart.yaml` version:
    - `0.0.2` → `0.0.3`

- **Representative change**
  ```bash
  - redis-cli -h localhost -p $REDIS_PORT ping
  + valkey-cli -h localhost -p $REDIS_PORT ping
  ```
