This is the first time I think in the otel params... would it make sense to add them as a secret? WDYT?

Agreed, otel-auth-token could be handled as a secret. What about other otel params such as otel-endpoint, otel-index, etc?

Moved otel-auth-token to the ibmcloud credential secret — it's now read from the secret mount with a graceful fallback if absent. The other otel params (endpoint, index, app-code, extra-attrs) are non-sensitive config, so kept them as plain params. Also added zone as a plain param for IC_ZONE per CodeRabbit's suggestion.

Address PR review feedback: - Move otel-auth-token from plain Tekton param to the ibmcloud credential secret (read from mount with fallback) - Add zone param for IC_ZONE when subnet-id is not provided - Print IC_ZONE in debug output
Move all OpenTelemetry params (auth-token, endpoint, index, app-code, extra-attrs) from the ibmcloud credential secret and plain Tekton params into a dedicated optional otel-credentials secret. This decouples observability config from cloud provider credentials, making the otel secret reusable across future cloud targets (e.g. AWS, GCP).

Sorry I did not track your comment. I was thinking otel to have its own secret.
With fields:
- otel-token
- otel-app-code
- otel-endpoint
- otel-index
Typically the token will be valid for that combination so probably it make sense to have them together
