text: Title: Airbyte provider 415 issue
  Body: ### Apache Airflow Provider(s)
  
  airbyte
  
  ### Versions of Apache Airflow Providers
  
  airbyte provider version == 5.0.0
  
  ### Apache Airflow version
  
  2.10.5
  
  ### Operating System
  
  linux-arm64
  
  ### Deployment
  
  Official Apache Airflow Helm Chart
  
  ### Deployment details
  
  We're using the official helm chart with the Airflow `2.10.5` image in an `EKS 1.31.0` environment (arm based) with the Airbyte operator version `5.0.0` installed.
  Airbyte OSS is also deployed on the same cluster **with auto disabled**.
  
  ### What happened
  
  When trying to access Airbyte using the Airbyte sync operator using the default connection set as follows:
  `airbyte://http://<svc name>.<namespace>.svc.cluster.local/api/public/` (by following [this manual](https://airflow.apache.org/docs/apache-airflow-providers-airbyte/stable/connections.html)) we get error 415 (unsupported media type), which basically means there is an issue with the headers being set to Airbyte.
  
  The Airbyte connection requires a client key and secret, as stated in the manual I attached above, but Airflow is set to `no auth`. Could this be the issue?
  
  
  ### What you think should happen instead
  
  The Airbyte operator should send the right headers and sync the connector successfully.
  
  ### How to reproduce
  
  1. Install the official helm chart with the Airflow `2.10.5` image in an `EKS 1.31.0` environment (arm based) with the Airbyte operator version `5.0.0` installed.
  
  2. Deploy Airbyte OSS version `1.2.0` and set it to "no auth"
  
  3. Create a basic connector of any kind in Airbyte and copy its ID.
  4. Create a default connection for Airbyte in the airflow environment by setting the appropriate env var.
  5. Write a sync dag for Airbyte.
  6. Trigger the dag and watch the results.
