Configuration warning

[dlpigpen]

In the deployment phase, i got a few warning logs like this:

Serverless: Configuration warning:
Serverless:   at 'layers.selenium': unrecognized property 'CompatibleRuntimes'
Serverless:   at 'layers.chromedriver': unrecognized property 'CompatibleRuntimes'
Serverless:  
Serverless: Learn more about configuration validation here: http://slss.io/configuration-validation

Seems like this repo isn't being updated, but I'm getting the same error.

I have found that this format works

layers:
  selenium:
    path: selenium
    compatibleRuntimes:
      - "python3.6"
  chromedriver:
    path: chromedriver
    description: chrome driver layer
    compatibleRuntimes:
      - "python3.6"
