Fix RequiredResourceAccess cannot be an array issue in Set-AzureADMSApplication

[PenguinCats]

Why we have this PR

When using Set-EntraApplication -ApplicationId $application.Id -RequiredResourceAccess $requiredResourceAccess, the $requiredResourceAccess could be an array. For example:

$requiredResourceAccess = @(
    @{resourceAppId = '00000003-0000-0000-c000-000000000000'
        resourceAccess = @(
        @{
            id = 'c79f8feb-a9db-4090-85f9-90d820caa0eb'
            type = 'Scope'
        },
        @{
            id = '9a5d68dd-52b0-4cc2-bd40-abcf44ac3a30'
            type = 'Role'
        })
    },
    @{resourceAppId = '11111111-0000-0000-c000-000000000000'
        resourceAccess = @(
        @{
            id = '11111111-a9db-4090-85f9-90d820caa0eb'
            type = 'Scope'
        },
        @{
            id = '11111111-52b0-4cc2-bd40-abcf44ac3a30'
            type = 'Role'
        })
    }
)
Set-EntraApplication -ApplicationId $application.Id -RequiredResourceAccess $requiredResourceAccess

In current logic, the input array will be converted into a single json string. However, the Set-EntraApplication is actually calling Update-MgApplication command, which requires input -RequiredResourceAccess <IMicrosoftGraphRequiredResourceAccess[]>. Reference here. This single string cannot be converted into IMicrosoftGraphRequiredResourceAccess[], causing the following error:

How to fix in the PR

We convert the parameter into string[], each json string can be converted into IMicrosoftGraphRequiredResourceAccess correctly.
