[v3-1-test] Use `exc_info` for task instance heartbeat failure exception
logging (#57172) (#57179)
closes: https://github.com/apache/airflow/issues/57167
PR #52562 changed `_handle_heartbeat_failures()` to accept an exception
parameter and log it as a structured field. Now due to this change, during the
first failed heartbeat attempt, the _handle_heartbeat_failures function logs a
message by calling log.warning(), which accepts an exception parameter that
expects a string type object. However, in the source code, [an exception type
object is
passed](https://github.com/apache/airflow/blob/54bd5d8cd9f6f477cc83445737614dec81c4323c/task-sd
[...]
The error looked like this:
```python

```
The change in #52562 was mainly made due to ruff upgrade reasons, so I am
going back to using the standard Python logging pattern: pass exception to
`exc_info` parameter.
After changes, error looks like this:
