Move hook to after:aws:deploy:deploy:updateStack rather than after:deploy:deploy

I'm attempting to have a single source project containing both React app and serverless spec, and have sls deploy:

1. Deploy backend resources to AWS
2. Use serverless-stack-output to update React app with details from CloudFormation
3. Run npm build
4. Use serverless-s3-sync to copy the React build/ directory up to S3.

Currently both serverless-stack-output and serverless-s3-sync run off after:deploy:deploy asynchronously. I'm not sure there's a way of defining the ordering or dependency between them without writing my own plugin, but it might be sufficient to move CloudFormation stack output earlier (and S3 sync later). Alternatively, is it related to #18?

I think this could be achieved by changing after:deploy:deploy to before:deploy:finalize in index.js.

I think this is sensible to go off the AWS-specific event, given it's specifically dealing with CloudFormation.

Yep, the above is an issue of:

• Ordering in serverless.yml
• Using a version of serverless-stack-output that uses a promise (e.g. @lucas-carneiro/serverless-stack-output)
