**Describe the bug**

Running shell script in Azure Devops pipeline is failing with below error intermittently-

`2024-07-15T05:35:32.5689287Z An error occurred (InvalidSignatureException) when calling the ListImages operation: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.`

**To reproduce**

Steps to reproduce the behavior:
1. Go to Azure Devops Pipeline and Create a task using AmazonWebServices.aws-vsts-tools.AWSShellScript.AWSShellScript
2. Call a script from repo/inline shell script
3. Run pipeline

**Screenshots**

**Your Environment**

- On-prem or cloud based: Cloud based
- Azure DevOps version: Version Dev19.M241.1 (AzureDevOps_M241_20240710.23)
- AWS Toolkit for Azure DevOps version:1.14.0 (Latest)

**Additional context**

Start with the AWSShellScript task and reproduce the intermittent InvalidSignatureException in an Azure DevOps pipeline using AWS Toolkit for Azure DevOps 1.14.0. Trace the request-signing path involved in the ListImages operation; done means the shell task executes successfully without intermittent signature errors.
