(GH-2334) (notepadplusplus.commandline)(notepadplusplus.install) Stop relaunch as Admin

[pauby]

NOTE: This will require pushing a package fix version.

Description

Removes relaunching Notepad++ as part of the package.

Motivation and Context

This fixes #2334: the problem that launching the application does so in the context of the elevated Chocolatey CLI session.

How Has this Been Tested?

This replaces the Write-Host text and removes the Start-Process that launched the application in the elevated context.

I think we eventually should look at how we can launch the application in non-admin mode, but for now I think it is fine.

So, LGTM.
