Issue:
amazon.aws.ec2_instance throws deprecation warning for teardown
### Summary

There is a deprecation warning "Default value instance_type has been deprecated, in the future you must set an instance_type or a launch_template. This feature will be removed from amazon.aws in a release after 2023-01-01."  I think this makes sense, except that this particular module does not need the instance_type set at all if you are doing `state: absent`.  I am not sure if we just document this... or if the warning needs to be clear to ignore if you are doing state: absent, or if we can be smart enough to not display the warning if you are doing state: absent.

@IPvSean Thank you for raising this. I guess we can easily reduce the scope of this warning to specific states. Do you agree @jillr?
