### Apache Airflow version

2.6.1

### What happened

The type of the libraries field in the DatabricksSubmitRunOperator is incorrect. According to the Databricks docs, the values should look more like:

```python
[
    {"pypi": {"package": "simplejson"}},
    {"pypi": {"package": "Faker"}},
]
```

as opposed to what the type hint implies:

```python
[
    {"pypi": "simplejson"},
    {"pypi":  "Faker"},
]
```
