Export-AzAutomationRunbook does not return path correctly if OutputFolder is set

### Description

Running the command

```
Export-AzAutomationRunbook -AutomationAccountName $AutomationAccountName -ResourceGroupName $AutomationAccountResourceGroupName -Name $RunbookName -OutputFolder $Env:TEMP -Force
```

from any working directory other than the local temp folder causes the returned file object to be invalid

It appears that there is a hardcoded assumption that the file is being exported to the local working directory and as such the file object returned has the full path of $WorkingDirectory\RunbookName.ps1

The file is successfully exported to the correct location so its just an script output issue

### Issue script & Debug output

```PowerShell
Export-AzAutomationRunbook -AutomationAccountName $AutomationAccountName -ResourceGroupName $AutomationAccountResourceGroupName -Name $RunbookName -OutputFolder $Env:TEMP -Force
```

Start with the Export-AzAutomationRunbook entry point and reproduce the command from a working directory different from OutputFolder. Compare the returned file object's path with the actual exported file; done means the returned object points to the file in the specified OutputFolder.
