### Official Helm Chart version

1.2.0

### Apache Airflow version

2.1.4

### Kubernetes Version

v1.21.6+bb8d50a

### Helm Chart configuration

I defined a new Connection String for AIRFLOW_CONN_SPARK_DEFAULT in values.yaml like the following section (base64 encoded or with correct string (spark://k8s://100.68.0.1:443?deploy-mode=cluster):

```
extraSecrets:
  '{{ .Release.Name }}-airflow-connections':
     data: |
       AIRFLOW_CONN_SPARK_DEFAULT: 'c3Bhcms6Ly9rOHM6Ly8xMDAuNjguMC4xOjQ0Mz9kZXBsb3ktbW9kZT1jbHVzdGVy'
```

in Section extraEnvFrom i defined the following:

```
extraEnvFrom: |
   - secretRef:
       name: '{{ .Release.Name }}-airflow-connections'
```

### Docker Image customisations

added apache-airflow-providers-apache-spark to base Image

### What happened

Airflow Connection mapped wrong because of the k8s:// within the url.  if i ask for the connection with cmd "airflow connections get spark_default" then host=k8s and schema=/100.60.0.1:443 which is wrong

### What you expected to happen

the spark Connection based on k8s (spark://k8s://100.68.0.1:443?deploy-mode=cluster) should be parsed correctly

### How to reproduce

define in values.yaml

```
extraSecrets:
  '{{ .Release.Name }}-airflow-connections':
     data: |
       AIRFLOW_CONN_SPARK_DEFAULT: 'c3Bhcms6Ly9rOHM6Ly8xMDAuNjguMC4xOjQ0Mz9kZXBsb3ktbW9kZT1jbHVzdGVy'

extraEnvFrom: |
   - secretRef:
       name: '{{ .Release.Name }}-airflow-connections'
```
