Change Type to AdminCenter

Small correction. No spaces are permitted in the Type for an extension so it stood out.

Verified that the Type is AdminCenter based on the New-AzConnectedMachineExtension command in <https://learn.microsoft.com/windows-server/manage/windows-admin-center/azure/manage-arc-hybrid-machines#automate-windows-admin-center-deployment-using-powershell>.
