Cannot delete Custom Role

### Description

I created a custom role through a PowerShell script for some use-case testing. After usage, I tried to delete the role, but it seems that I cannot delete it both from the Azure Portal and through PowerShell commands.

I noticed that the custom role created did not create its own DefinitionName.

### Issue script & Debug output

```PowerShell
No output

### Error output

_No response_

No repository file, test, or concrete PowerShell command is identified. Start by reproducing custom-role creation and deletion in Azure Portal and PowerShell, then investigate why the role lacks a DefinitionName; done means the same custom role can be deleted through both paths.
