[BUG]: Azure Powershell credentials fail to refresh on linux agents when running in parallel

### Task name

AzurePowershell

### Task version

5.257.0

### Issue Description

We have a pipeline that runs an AzurePowershell task to interact with several of our Azure resources. We recently added parallelism to the task, but that is now causing our Linux build agents to fail with this error:

```
Get-AzStorageAccount: ‌
Line |‌
     7 | ‌ … eContext = (‌Get-AzStorageAccount -ResourceGroupName $resourceGroupNam‌ …‌
        | ‌               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~‌
        | ‌Your Azure credentials have not been set up or have expired, please run Connect-AzAccount to set up your Azure credentials.‌
ClientAssertionCredential authentication failed: Persistence check failed. Data was written but it could not be read. Possible cause: on Linux, LibSecret is installed but D-Bus isnt running because it cannot be started over SSH.‌
```

We are unable to call Connect-AzAccount again, because that was called by the Azure Powershell task using our Service Connection credentials that we don't have access to inside of our script.

When we run this pipeline on a Windows build agent, it succeeds--the credentials are only failing to refresh on Linux build agents.
