Code Blocks in Documentation should not contain the PowerShell prompt

[TBemrose]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

GitHub provides a 'copy' button on code blocks. Code blocks should only contain code, no prompt strings, since they will get copied as well.

For example, docs/Microsoft.PowerShell.ConsoleGuiTools/Out-ConsoleGridView.md:40-42 has the following:

PS C:\> Get-Process | Out-ConsoleGridView

When you click the 'copy' button on this code block, it will copy "PS C:> " in addition to the intended code.

Expected behavior

I expected to be able to click the 'copy' button, paste into PS, hit ENTER and view the results.

Actual behavior

The "PS C:\> " prompt got copy-pasted and screwed everything up when I hit ENTER.

PS: 2 C:\> PS C:\> Get-Process | Out-ConsoleGridView
Get-Process: A positional parameter cannot be found that accepts argument 'Get-Process'.
