chore: update title casing for consistency in page and navigation

[jkmdev]

Description

Fixes #1394
Changes how the docusaurus sidebar for fast-dna packages displays their titles via the build/documentation/copy-package-readme.js script; uses the title in the package readme.md files to determine formatting/casing. Also renames one of the package readme files so it is recognized by the script.

I was considering using a json file to store this title information instead and drawing from there. I went with this current method because it would be less work to maintain but it relies on how the readme.md files are formatted (e.g. the package title needs to be the first line with text for this script to work). If there's a preference for the former approach I can switch to that one.

Motivation & context

The titles in the docusaurus sidebar wasn't conforming to the proper style guidelines, this change fixes that.
