Serverless-chrome: Update the example to use node8.10 by 30/04/2019 - Node 6 is being deprecated on AWS Lambda

[saborrie]

AWS sent me this email:

Invokes for functions configured to run on node.js 6.10 will continue to work normally, however the ability to create new Lambda functions configured to use the node.js 6.10 runtime will be disabled on April 30 2019. Code updates to existing functions using node.js 6.10 will be disabled 30 days later on May 30 2019

7 days to go until Amazon drop support and the example and the quick start on this repo stop working.

This won't work after 30/4:
serverless create -u https://github.com/adieuadieu/serverless-chrome/tree/master/examples/serverless-framework/aws

Ok well time to close this one because you missed out entirely on node 8 which is now also being deprecated.
