Fix Test-Remainder invocation to pass three arguments, not two.

You state: "The following example declares a Value parameter that's mandatory and a Remaining parameter that accepts **all the remaining parameter values** that are submitted to the function.

You want to demonstrate this with this invocation:
`Test-Remainder first one, two`

But your "all the remaining parameter values" is merely one value: `one, two` is an array.
Thus, if you removed `ValueFromRemainingArguments`, the same invocation would yield the same output, so your example **does not** demonstrate the benefit of `ValueFromRemainingArguments`.
To fix it, three args have to be passed to the Cmdlet, not just two.
