How to use DefaultAzureCredential in plugin for backup on azure blob storage

Hi @dosu, as per below PR feat: add support for DefaultAzureCredential authentication mechanism #681

This commit adds support for the DefaultAzureCredential authentication mechanism in Azure Blob Storage. Users can now use the useDefaultAzureCredentials option to enable Azure's default credential chain, which automatically discovers and uses available credentials in the following order

Environment Variables (Service Principal)
Managed Identity
Azure CLI
Azure PowerShell
This is particularly useful when running on Azure Kubernetes Service (AKS) with
Workload Identity, eliminating the need to explicitly store credentials in
Kubernetes Secrets.

This will merge in 0.11.0 version.
But can you please tell me if i want to use this what i need to configure . I don’t know ant to use credentials or sas token directly. So will i required to use workload identity or managed identity. Could you please tell what is difference between managed identity and workload identity?

查看 PR #681 以及 issue 中描述的 useDefaultAzureCredentials 选项，然后确定 Azure Blob Storage 身份验证文档的入口。记录所需的配置，并清楚区分 managed identity 和 workload identity，同时提供涵盖所提到的凭据选项的示例；当用户无需后续提问即可选择并配置身份验证方式时，即视为完成。
