Update Backup-AzRecoveryServicesBackupItem.md

Hi,

I've made 2 changes in the Example. Actually there is a parameter called "-FriendlyName", not just "Name"

And the other one, is on the last cmdlet, it is missing a "BackupItem" in the final of the cmdlet.

$Job = Backup-AzRecoveryServicesBackupItem -Item $Item


$NamedContainer = Get-AzRecoveryServicesBackupContainer -ContainerType AzureVM -Status Registered -FriendlyName "pstestv2vm1"
