Add "Where did it install to?" page

## What New Or Updated Would You Like To See?

I think adding a page describing installation locations would be appropriate.

- It probably should start off with a snippet describing the difference between a package and the software a package installs.
- Then describe where packages get installed to (e.g. under `$env:ChocolateyInstall\lib`)
- Then describe where portable software gets installed (In the lib folder or in `Get-ToolsLocation` normally)
- Then talk about various installation type packages, and how to find where installers put the software (like the `Software installed to...` message)
- And discuss template and extension package install locations
- And cover packages that don't install any software (meta packages, configuration changes), or where there is not a simple installation location (windows update packages)

## Why Is It Needed?

I have seen a number of issues/comments/discussions in various places with people having difficulty finding where a package actually put the software, in many cases stemming from not fully understanding how Chocolatey packages work. https://github.com/chocolatey/choco/issues/1929

## Additional Context?

This should go alongside changes to help people find the installation location after the package is installed:
