update docs for local deployment of rollup (#22)

## Description
Removes repeated instructions and adds clarity to the "Overview" and
"Local Deployment" on dusknet sections.

## Motivation and Context
Make sure docs are clear and easy to follow- existing docs had repeated
instructions and had parts that were missing clarity.

## Types of changes
<!-- What types of changes does your code introduce? Put an `x` in all
the boxes that apply: -->
- [X] Edits to existing documentation
- [ ] Changing documentation structure (relocating existing files,
ensure redirects exist)
- [ ] Stylistic changes (provide screenshots above)
