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

Note

Low Risk
Markdown-only link, branding, and formatting fixes with no runtime, security, or dependency impact.

Overview
This PR updates repository markdown only—no code or build behavior changes.

CONTRIBUTING.md standardizes GitHub capitalization (section title and workflow bullets) and points the index.rst doc entry link at docs/labelbox/index.rst instead of the old docs/source/ path.

The root README.md switches the social badge from Twitter to X (x.com), adds Provenance to the table of contents and drops the dead “Develop with AI Assistance” entry, fixes the API key doc URL to docs.labelbox.com/reference/create-api-key, uses GitHub in support text, and adds python / bash fences on the Jupyter and provenance examples.

libs/labelbox/README.md uses the same API key reference link and closes the docs code block properly. libs/lbox-clients and libs/lbox-example shorten the experimental notice and remove the link to product-release phases that no longer documents “Experimental.”
