Fix flaky Glue OpenLineage test that calls the real AWS endpoint

[FrankYang0529]

Why

• The test_inject_parent_job_info_with_resume_on_retry patches GlueJobHook.get_conn, but GlueJobOperator reads self.hook.conn. AwsBaseHook.conn calls get_client_type() and doesn't go through get_conn(), so the patch has no effect and the test builds a real boto3 Glue client. The CI result timeout sometimes.

How

• Assign glue.hook.conn before execute() and stub get_job_runs to return an empty JobRuns list.

Verification

• uv run --project providers/amazon pytest providers/amazon/tests/unit/amazon/aws/operators/test_glue.py -q
