### What happened

The deprecated variable `execution_date` raises an error when used in an f string template with date string formatting.

```python
In [1]: execution_date
DeprecationWarning: Accessing 'execution_date' from the template is deprecated and will be removed in a future version. Please use 'logical_date' or 'data_interval_start' instead.
Out[1]: <Proxy at 0x7fb6f9af81c0 wrapping DateTime(2021, 11, 18, 0, 0, 0, tzinfo=Timezone('UTC')) at 0x7fb6f9aeff90 with factory <function TaskInstance.get_template_context.<locals>.deprecated_proxy.<locals>.deprecated_func at 0x7fb6f98699d0>>

In [2]: f"{execution_date:%Y-%m-%d}"
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
----> 1 f"{execution_date:%Y-%m-%d}"

TypeError: unsupported format string passed to Proxy.__format__
```



### What you expected to happen

Executing `f"{execution_date:%Y-%m-%d}"` should return a string and not raise an error. 

### How to reproduce

```python
from datetime import datetime
from airflow import DAG
from airflow.operators.python import PythonOperator


def test_str_fmt(execution_date: datetime):
    return f"{execution_date:%Y-%m-%d}"


dag = DAG(
    dag_id="Test_Date_String",
    schedule_interval="@daily",
    catchup=False,
    default_args={
        "depends_on_past": False,
        "start_date": datetime(2021, 11, 1),
        "email": None,
        "email_on_failure": False,
        "email_on_retry": False,
        "retries": 0,
    },
)

with dag:
    test_task = PythonOperator(
        task_id="test_task",
        python_callable=test_str_fmt,
    )
```

### Anything else


```python
from datetime import datetime
...
datetime.fromisoformat(next_ds)
TypeError: fromisoformat: argument must be str
```
