[Docs] Apply Google style guide to development.rst

Apply Google developer documentation style guide rules to development.rst:

- Sentence case: fix 11 headings (Source, Steps, Only, Full Source Build, MacOS, Development Tooling, Pre-commit Hooks, Advanced Build Options, Fast/Debug/Optimized Builds, Building the Docs)
- Second person: replace "We provide" with "Use the script"
- Present tense: replace future "will" constructions throughout (env var list, prose sections)
- Contractions: "Do not" -> "Don't", "will not" -> "won't", "pip is not" -> "isn't"
- Active voice: env var list passive constructions converted ("will be built" -> "Ray builds", etc.)
- macOS branding: fix "MacOS" -> "macOS" and "mac" -> "Mac" throughout
