### Helm Chart Version

0.445.3

### What step the error happened?

Upgrading the Platform or Helm Chart

### Relevant information

# Problem

I'm attempting to set up my OSS Airbyte deployment to use GCS logging. Relevant chart values are below (from a FluxCD patch):

```yaml
apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
name: airbyte
spec:
values:
global:
# gcs-credentials-ext is a secret that contains the GCS credentials, created externally to the helm deployment
storage:
type: "GCS"
storageSecretName: gcs-credentials-ext
bucket:
log: my_log_bucket
state: my_log_bucket
workloadOutput: my_log_bucket
```

`gcs-credentials-ext` was created externally to the Helm chart deployment, as I wanted to avoid having my base64 encoded credentials held in source control at `global.storage.gcs.credentialsJson`

# Analysis

When I run the helm install, the pod for `airbyte-workload-api-server` gets stuck in the `ContainerCreating` state, with the following error:

`Warning FailedMount 3s (x4 over 6s) kubelet MountVolume.SetUp failed for volume "gcs-log-creds-volume" : secret "airbyte-gcs-log-creds" not found`

Upon analysis of the workload API server template, this is due to the `secretName` defaulting to `releasename-gcs-log-creds` because it is looking for a value `.Values.global.credVolumeOverride`). See - https://github.com/airbytehq/airbyte-platform/blob/f8146bdc352726509bc5bbd8870052e666178944/charts/airbyte-workload-api-server/templates/deployment.yaml#L202

This is at odds with the other components that refer to the same secret (they all use `Values.global.storage.storageSecretName`):

* Workload launcher - https://github.com/airbytehq/airbyte-platform/blob/f8146bdc352726509bc5bbd8870052e666178944/charts/airbyte-workload-launcher/templates/deployment.yaml#L596
* Worker - https://github.com/airbytehq/airbyte-platform/blob/f8146bdc352726509bc5bbd8870052e666178944/charts/airbyte-worker/templates/deployment.yaml#L587
* Server - https://github.com/airbytehq/airbyte-platform/blob/f8146bdc352726509bc5bbd8870052e666178944/charts/airbyte-server/templates/deployment.yaml#L516

# Proposal

I propose that this line https://github.com/airbytehq/airbyte-platform/blob/f8146bdc352726509bc5bbd8870052e666178944/charts/airbyte-workload-api-server/templates/deployment.yaml#L202, be changed from:

`secretName: {{ ternary (printf "%s-gcs-log-creds" ( .Release.Name )) (.Values.global.credVolumeOverride) (eq .Values.global.deploymentMode "oss") }}`

to:

`secretName: {{ ternary (printf "%s-gcs-log-creds" ( .Release.Name )) .Values.global.storage.storageSecretName (not ((.Values.global.storage).storageSecretName)) }}`
