Add Semantic Convention Support for Amazon Secrets Manager Attributes

This PR adds the aws.secretsmanager.secret.arn semantic convention attribute for the following AWS resources:

AWS Secrets Manager SDK

The Secret ARN is extracted from both request and response objects, and this behavior is covered by unit tests.

Tests Run:
npm run compile
npm run lint
npm run test

All newly added tests pass, and no regressions were found.

Backward Compatibility:
This change is fully backward compatible. It introduces instrumentation for an additional AWS resource without modifying existing behavior in the auto-instrumentation library.
