[Feature]: Add "-AsJob" Parameter to "New-AzOperationalInsightsWorkspace"

### Description of the new feature

I would like to have the option to create a Workspace with the Parameter "-AsJob".

```
ModuleType Version PreRelease Name ExportedCommands
---------- ------- ---------- ---- ----------------
Script 2.3.1 Az.OperationalInsights
```

### Proposed implementation details (optional)

_No response_

Start at the New-AzOperationalInsightsWorkspace entry point in the Az.OperationalInsights module and inspect how related cmdlets handle -AsJob. Confirm that this cmdlet accepts -AsJob and that workspace creation reports the expected job behavior, using the module's existing test entry points if available.
