This PR prevents the Airflow 3 Supervisor process from crashing entirely
when transient network or IAM errors occur during Stackdriver log transmission.
## Description
This PR addresses **Bug 3** described in #68240.
In the new Airflow 3 Task SDK architecture, the `StackdriverRemoteLogIO`
handler runs within the Supervisor process rather than the task process itself.
If an exception is raised during `_transport.send()`, it propagates upwards and
crashes the entire Supervisor process, disrupting task monitoring.
### Key changes
* **Exception Handling**: Wrapped the `_transport.send()` call in a
`try...except Exception` block. When a transmission fails, the exception is
safely caught, and a warning is logged using the internal `_logger`. This
ensures the Supervisor process remains highly resilient.
## Verification Results
I have verified the changes using `prek` and `breeze`.
* **Static Checks (Prek):** Passed
* **Unit Tests (Breeze):** Passed
