fix: Queue visibility time has to be >= lambda timeout (#467)

* AWS SQS queue visibility times have to be >= the timeout of the associated lambda
* error to do so will result in a terraform provisioning error during initial resource creation (apparently not a modification)
* hence, setting module.runners.aws_sqs_queue.queued_builds.visibility_timeout_seconds  to module.runners.module.runners.aws_lambda_function.scale_up.timeout
