commit 8210f69505ce5c45213ec82f0d993bf7677ba864
Author: Kaxil Naik <kaxiln...@apache.org>

    Fix SSHHookAsync defaulting no_host_key_check to False unlike SSHHook 
(#64225)
    
    SSHHook (sync) defaults no_host_key_check=True, but SSHHookAsync
    defaults to False when the option is not set in connection extras.
    This causes SSHRemoteJobOperator to submit jobs successfully (via
    the sync hook on workers) but the triggerer fails to poll completion
    because the async hook rejects the host key.
    
    Align the async hook default with the sync hook so both skip host
    key verification when no_host_key_check is not explicitly configured.
