### Apache Airflow version

### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
Task SDK not able to read asset events
**Error**

### What you think should happen instead?
We should be able to fetch asset events in AF3 as we are able to do in AF2.
### How to reproduce
Create Asset events with below DAG
```
ds = Dataset("s3://output/1.txt")
with DAG(
dag_id="dataset_with_extra_by_yield",
catchup=False,
start_date=datetime.datetime.min,
schedule="@daily",
tags=["datasets"],
):
@task(outlets=[ds])
def dataset_with_extra_by_yield():
yield Metadata(ds, {"hi": "bye"})
dataset_with_extra_by_yield()
with DAG(
dag_id="dataset_with_extra_by_context",
catchup=False,
start_date=datetime.datetime.min,
schedule="@daily",
tags=["dataset"],
):
@task(outlets=[ds])
def dataset_with_extra_by_context(*, outlet_events=None):
outlet_events[ds].extra = {"hi": "bye"}
dataset_with_extra_by_context()
```
Now try to retrieve them with below DAG
```
ds = Dataset("s3://output/1.txt")
with DAG(
dag_id="read_dataset_event",
catchup=False,
start_date=datetime.datetime.min,
schedule="@daily",
tags=["datasets"],
):
@task(inlets=[ds])
def read_dataset_event(*, inlet_events=None):
print(f"inlet_events are {inlet_events}")
for event in inlet_events[ds][:-2]:
print(event.extra["hi"])
read_dataset_event()
```
