Fixes typos and documentation mismatch in PR #1054

What is in this Pull Request ?

• Fixes typos, docs mismatch and improve consistency across Doc examples
• Converted CommentsEnabled argument to be a switch parameter instead of a nullable boolean
• The AddPnPClientSidePage cmdlet has now the Name argument as first position (It allows to use "Add-PnPClientSidePage "mypage" )
• Ensures the ClientSidePagePipeBind has always a value for the _name field. When the piped object is a ClientSidePage object, the name of the underlying file is fetched.

@erwinvanhunen I have a little question here.
Why are the -Section and -Column of the AddClientSideText and AddClientSideWebPart are narked as mandatory since it is, functionally speaking, not mandatory to set the position of the component ?

[EDIT] Nevermind, I just got up to speed with the ParameterSetName attribute ;)

Good fixes!
