Configuration.host is really a URL not a host

I passed `host = 'https://domain.of.my.instance'` to the Configuration object and all I got was a lousy HTML ~~(t-shirt material right there)~~.

```python
import os
import sys
import authentik_client

def main():
host = os.environ.get("AUTHENTIK_HOST")
token = os.environ.get("AUTHENTIK_TOKEN")
if not token:
print("AUTHENTIK_TOKEN unset")
sys.exit(1)

if not host:
print("AUTHENTIK_HOST unset")
sys.exit(1)

configuration = authentik_client.Configuration(
host=host,
access_token=token
)

with authentik_client.ApiClient(configuration) as api_client:
# Create an instance of the API class
api_instance = authentik_client.AdminApi(api_client)
try:
api_response = api_instance.admin_apps_list()
print("The response of AdminApi->admin_apps_list:\n")
print(api_response)
except authentik_client.ApiException as e:
print("Exception when calling AdminApi->admin_apps_list: %s\n" % e)

if __name__ == "__main__":
main()
```

When invoking it I got:

```
python move-okta-app-to-authentik.py
Exception when calling AdminApi->admin_apps_list: (404)
