[Feature]: Set-AzActivityLogAlert add more abilities the ARM template has. e.g. ActionGroupId.

### Description of the new feature

In short I would want Set-AzActivityLogAlert, to be on par with New-AzMetricAlertRuleV2Criteria. I assume once it does it will get it's own page in Azure Service Health alerts. Another way to put this would be great if Set-AzActivityLogAlert could do more of the features available in the ARM template.

One example of an instance where this is not the case is ActionGroups:

In the Portal & ARM you can assign any ActionGroup type to an Health Service Alert / ActivityLog Alert. But in powershell "ActivityLogAlertActionGroup" is the only ActionGroup **type** that works with Set-AzActivityLogAlert,

Another is region;
According to this issue https://github.com/Azure/azure-powershell/issues/10135, impacted Region is accessible from powershell but not according to the documentation. https://docs.microsoft.com/en-us/powershell/module/az.monitor/new-azactiongroup?view=azps-7.5.0. I have yet to test this, it would be good to have, so maybe the documentation is behind.

Another is ServiceHealthServices..

Edits;
I have made a number of edits to improve clarity.
