### Versions of Apache Airflow Providers

apache-airflow-providers-microsoft-azure==3.1.1

### Apache Airflow version

2.1.2

### Operating System

OSX 

### Deployment

Docker-Compose

### Deployment details

_No response_

### What happened

`_get_blob_client` method in the wasb hook is trying to create a container


### What you expected to happen

I expect to get a container client of an existing container

### How to reproduce

_No response_

### Anything else

I believe the fix is minor, e.g.

```
def _get_blob_client(self, container_name: str, blob_name: str) -> BlobClient:
        """
        Instantiates a blob client

        :param container_name: The name of the blob container
        :type container_name: str
        :param blob_name: The name of the blob. This needs not be existing
        :type blob_name: str
        """
        container_client = self.create_container(container_name)
        return container_client.get_blob_client(blob_name)
```

should be changed to 

```
def _get_blob_client(self, container_name: str, blob_name: str) -> BlobClient:
        """
        Instantiates a blob client

        :param container_name: The name of the blob container
        :type container_name: str
        :param blob_name: The name of the blob. This needs not be existing
        :type blob_name: str
        """
        container_client = self._get_container_client(container_name)
        return container_client.get_blob_client(blob_name)
```
