Version 3.389.0

• Aws\Handler - Adds Guzzle 8 support.
• Aws\ApplicationInsights - This release adds Smithy RPC v2 CBOR as an additional protocol alongside the existing AWS JSON 1.1. The SDK will prioritize its most performant protocol.

• Aws\DynamoDB - Endpoint test standardizations
• Aws\CognitoIdentityProvider - Amazon Cognito user pools now support the AdminGetUserAuthFactors operation, which lets administrators retrieve the configured authentication factors (such as password, SMS, email, and TOTP) available for a specific user in a user pool.
• Aws\NeptuneGraph - Update validations for Tag Keys and KMS Key ARNs.
• Aws\Odb - Documentation-only update to clarify the operation-specific valid values for the externalIdType field.
