### Description

Following #29282, command timeout is set at the `SSHHook` level while it used to be able to set at the `SSHOperator` level.

I will work on a PR as soon as i can.

### Use case/motivation

Ideally, i think we could have a default value set on `SSHHook`, but with the possibility of overriding it at the `SSHOperator` level.
