Set-AzSecurityPricing -Name "AppServices" -PricingTier "Standard" throws error "Set-AzSecurityPricing: Internal server error has occurred"

### Description

I am trying to enable Defender for Cloud features using the PowerShell commands.
Set-AzSecurityPricing -Name "AppServices" -PricingTier "Standard" throws an error "Set-AzSecurityPricing: Internal server error has occurred". It used to work on previous versions of Az PowerShell. Issue started appearing after I upgraded to Az 11.0.0.

### Error output

_No response_

Start by reproducing Set-AzSecurityPricing -Name "AppServices" -PricingTier "Standard" with Az.Security 1.5.0 and compare it with the listed 1.4.0 behavior. Read the SetPricings cmdlet and PricingOperations.UpdateWithHttpMessagesAsync entry points shown in the stack trace, then verify that the command no longer returns the 2023-01-01 Microsoft.Security pricing API internal-server error.
