Update laps-technical-reference.md

Fixed cmdlet to not include the word 'PowerShell'.
The previous command was wrong:

PS C:\> Update-LapsADSchema PowerShell
Update-LapsADSchema : A positional parameter cannot be found that accepts argument 'PowerShell'.
At line:1 char:1
+ Update-LapsADSchema PowerShell
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Update-LapsADSchema], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.Windows.LAPS.UpdateLapsADSchema

With the fixed command it works:

PS C:\> Update-LapsADSchema

The 'ms-LAPS-Password' schema attribute needs to be added to the AD schema.

The fix looks good to me (I am the original author so this is my bug :)).

Would an official "someone" please approve this change for Martin?
