## Problem
`BigQueryAsyncHook._get_job()` calls `sync_hook.get_job()` synchronously
inside an async method, blocking the event loop when running in triggers. This
is a regression from #56363 which removed the `async_to_sync` wrapping but left
the raw sync call in place.
## Root Cause
`_get_job` awaits `get_sync_hook()` correctly, but then calls
`sync_hook.get_job(...)` directly — a blocking I/O call that stalls the
trigger's event loop.
## Fix
Wrap the sync `get_job` call with `asgiref.sync_to_async` so it runs in a
thread pool, consistent with how `GoogleBaseAsyncHook` handles other
sync-to-async bridging (see `get_sync_hook`, `service_file_as_context`).
Added a unit test verifying `sync_to_async` is called.
Closes: #63182
