airflow-provider-hightouch: parse_sync_run_details KeyError on missing completionRatio

TL;DR

Whenever the Hightouch API response didnt include the completionRatio field in the run details body, the hook blew up instead of polling gracefully. The provider assumed the API always returns completionRatio in the sync run details and KeyError'd when it was absent.

Steps

1. With airflow-provider-hightouch 3.0.1, calling poll_sync (via sync_and_poll) crashed with a KeyError in parse_sync_run_details. Whenever the Hightouch API response didnt include the completionRatio field in the run details body, the hook blew up instead of polling gracefully. Full traceback in the thread.
2. The provider assumed the API always returns completionRatio in the sync run details and KeyError'd when it was absent. The reporter hit this on provider 3.0.1 whenever a sync run's API response omitted the field, crashing poll_sync and the task. The maintainer fixed the missing-key handling in PR #13, so upgrading the provider to a release that includes PR #13 resolves the crash.
