AWS::CloudFront::PublicKey Drift showing False positive due to escape character "\r" "\n"

Name of the resource

AWS::CloudFront::PublicKey

Resource Name

No response

Issue Description

AWS::Cloudfront::PublicKey is showing false positive when you run the drift on the resource. The resource created using CFN template and the describe call on resource have escape characters "\n" "\r" depending on how the EncodedKey value is passed to PublicKey, which is causing a drift since, CFN as well as CloudFront add these character based on the lines and spaces.

Expected Behavior

CFN should ignore escape character in EncodedKey value when comparing the resource or standardised the creation of resource for using escape characters

Observed Behavior

The False positive result for drift is shown when running drift against AWS::Cloudfront::PublicKey resource for EncodedKey value due to escape character "\n" "\r"
