Refactor Documentation for better UX

# 🚀 Feature Request

### Relevant Package [**REQUIRED**]

This feature request is for...
all the docs!

### Description [**REQUIRED**]
A clear and concise description of the problem or missing capability...

- re-read and potentially (if resources allow) do UX tests on the getting started instructions - is this something we want to keep up to date? (old references to past releases, previous go versions, and previous docker versions
- improve security section
- improve overarching style - do we want any instructions numbered? should we avoid the use of long paragraphs in the instructions? how can this be more user friendly - [these steps](https://docs.edgexfoundry.org/3.0/security/Ch-Configuring-Add-On-Services/) and [these steps](https://docs.edgexfoundry.org/3.0/security/Ch-RemoteDeviceServices/) required multiple read-throughs before the instructions were semi-clear
- improve the organization of each chapter - many chapters - like security, examples and tutorials to name a couple, seem to have pages in a random order - is there a way to group pages or better organize things so that users get a better sense of what information is present?

### Describe the solution you'd like
If you have a solution in mind, please describe it.
- determine a way to group information or present it better
- determine a consistent way to organize the documentation
- focus on usability and readability - both of which aren't the easiest if unfamiliar with the project

**Things that are hard to find:**
- it is hard to find information on the different targets or option with compose builder - is this documented anywhere? or is that up to the developers to figure out?
- it's pretty hard to find configuration information and appropriate values - if you don't know what you are looking for, it is nearly impossible to find without looking instead at the source code
- what are all the different compose-builder options- is there a list anywhere - how can users leverage this tool to help them build images for securing services or using services in a non-secure way.

### Describe alternatives you've considered
Have you considered any alternative solutions or workarounds?
