Bug Title

[Workload Identity] Azure CLI Not Installed

Crate Name

azure_identity

Crate Version

v0.22.0

Description

When using Workload Identity with the azure identity rust SDK, I am getting the following error in my service logs:

error getting token credential from Azure CLI - Azure CLI not installed

I didn't need to install the CLI on my NodeJS containers using the SDK. Just flagging in case I'm doing something wrong here.

Steps to Reproduce

1. Rust code:

let credential = DefaultAzureCredential::new()?;

2. Use Azure Workload Identity and run this code inside of a pod.
3. Get the error listed above

I used the DefaultAzureCredential because I figured the credential chain would use the workload identity eventually (this is how it works in Nodejs). Is that not the case. Should I be using WorkloadIdentityCredential?
