Scale up Cloudwatch Alarm Regex typo

[lucasklaassen]

Hey man, thanks for putting this together! I love how it works.

Just noticed when I tried to port this to my project that the scale up Cloudwatch alarm regex has a typo: https://github.com/sbstjn/sqs-worker-serverless/blob/master/functions/scale.js#L7

The Cloudwatch alarms that were set up for me had Message being singular instead of plural.

Maybe I misconfigured something but I believe we should update:

 const regex = /(OK|ALARM):(.*)MessagesAlarm([0-9]*)/g

to

 const regex = /(OK|ALARM):(.*)MessageAlarm([0-9]*)/g
