(doc) Make documentation consistent with practice

[pauby]

Description Of Changes

Make our documentation consistent with best practice and advice.

Motivation and Context

Our advice is for customers to set cacheLocation to $env:ChocolateyInstall\choco-cache (by default c:\programdata\chocolatey\choco-cache) but our documentation uses $env:ALLUSERSPROFILE\choco-cache (by default c:\programdata\choco-cache). We need to make sure they are consistent.
