Documentation Cleanup

Description

Documentation Cleaning

I started this to fix a couple of dead links in the root README.md but figured I should go ahead and hit other documentation while I was at it.

CONTRIBUTING.md

• Fix Capitalization "Github" -> "GitHub" in several places
• Contribution Guide
  • General Guidelines
    • Fixed Dead Link "index.rst"

README.md

• Badges
  • Twitter -> X
• Labelbox
  • Table of Contents
    • Remove Deadlink "Develop with AI"
    • Add Missing Section "Provenance"
  • Quick Start
    • Generate an API key
      • Fixed Dead Link "Account > API Keys"
    • Validate Installation and API Key
      • Fix Capitalization "Github" -> "GitHub"
  • Jupyter Notebooks
    • Added python syntax highlighting to code block
  • Provenance
    • Added bash syntax highlighting to the code block

Other

• Removed README.md links to definition of "Experimental Feature" in libs/lbox-clients and libs/lbox-example This redirected to the overview page and it appears that we no longer define what an experimental feature is in the docs.
• Fixed Dead Link to "Labelbox API key docs" in libs/labelbox/README.md.

Type of change

• Document change (fix typo or modifying any markdown files, code comments or anything in the examples folder only)

All Submissions

• Have you followed the guidelines in our Contributing document?
  • No, there's no reason for me to install devdependencies or spin up a virtual environment for changes to markdown documentation
• Have you provided a description?
• Are your changes properly formatted?

Note

Low Risk
Markdown and link updates only; no runtime code, dependencies, or build behavior changes.

Overview
Documentation-only cleanup across root and module READMEs: fixes broken or outdated links, standardizes GitHub capitalization, and improves markdown formatting.

In CONTRIBUTING.md, workflow headings and body text use GitHub consistently, and the index.rst doc entry points to docs/labelbox/index.rst instead of the old path.

The root README.md updates the social badge to X (x.com), refreshes the API key doc link, adds a Provenance TOC entry (and drops the stale “Develop with AI” link), uses GitHub Issue wording, and tags Jupyter and SLSA verification snippets as python / bash fenced blocks.

libs/labelbox/README.md points integration-test API key help at the current create-api-key reference and restores a closing fence on the docs command block. libs/lbox-clients and libs/lbox-example READMEs drop the dead “experimental feature” doc link and shorten the experimental disclaimer to plain HTML.
