deploy: Create AWS session for CloudFront invalidation via Go CDK

Browse source 
This allows the AWS credentials to be picked up from the configured
target URL (like blob does) rather than the current behaviour of only
relying on the defaults.

Relying on the defaults here means having to specify credentials twice
(once in the URL for the blob, once in the environment for this code
path) when non-default AWS credentials are in used (e.g. via a profile).
