### Apache Airflow version

Other Airflow 2 version (please specify below)

### What happened

Airflow Version 2.5.2

Issue: Create a connection of type azure blob storage using the method #3 described in [OSS docs](https://airflow.apache.org/docs/apache-airflow-providers-microsoft-azure/stable/connections/wasb.html). 

When we use the storage account name and the access key as in the below screenshot, the connection works just fine.

Then what is the purpose of the extra field called `Blob Storage Shared Access Key(Optional)`? When I tried to put the access key in this field, then connection fails with the below error on testing: 

```
invalid url http://
```
