Fixed bug in posh-docker setup instructions 

There were two problems that this fixes.

1. Before this change, posh-docker was being installed twice. Once for the system (via NuGet) and secondly in the user's PowerShell context. This was confusing. I understand the reason was probably to create the user's $PROFILE file if it didn't already exist. I've replaced that functionality with clearer code.

2. The instructions had incorrectly said to add "Install-Module posh-docker" to the $PROFILE. Instead, this needed to be "Import-Module posh-docker".

into the file:
```none
