Fix compatibility with nodejs 14.x

[jamesla]

The runtime and memory_size variables are strings and numbers so the lookup function fails since it requires a map.

The error is:

Error: expected runtime to be one of [nodejs nodejs4.3 nodejs6.10 nodejs8.10 nodejs10.x nodejs12.x java8 java8.al2 java11 python2.7 python3.6 python3.7 python3.8 dotnetcore1.0 dotnetcore2.0 dotnetcore2.1 dotnetcore3.1 nodejs4.3-edge go1.x ruby2.5 ruby2.7 provided provided.al2], got nodejs14.x

Can you give more some more context or how to reproduce the error?

The lookup itself seems fine since it got a value for runtime which is nodejs14.x.
The error here may come from an outdated AWS provider, I think support for nodejs14.x requires at least v3.27.0, see hashicorp/terraform-provider-aws#17450
