[Enhancement]: aws_signer_signing_profile support for new platform_id for container signing with notation

[polarctos]

Description

The AWS Signer service now also allows to sign container images.

For this a new platform_id was introduced, namely Notation-OCI-SHA384-ECDSA

Currently aws_signer_signing_profile only allows the platform_id for Lambda:

terraform-provider-aws/internal/service/signer/signing_profile.go

Lines 42 to 43 in 5a7eaa6

	ValidateFunc: validation.StringInSlice([]string{
	"AWSLambda-SHA384-ECDSA"},

Suggested fix, add the new Notation-OCI-SHA384-ECDSA value to the validation:

 ValidateFunc: validation.StringInSlice([]string{ 
 	"AWSLambda-SHA384-ECDSA", "Notation-OCI-SHA384-ECDSA"}, 

These two are currently exposed via the AWS Console:

API name	Display name
AWSLambda-SHA384-ECDSA	AWS Lambda
Notation-OCI-SHA384-ECDSA	Notation for container registries
