Docs site: Standardize example headers to Title Case and improve clarity

[balajis-qb]

Description

This PR refines and standardizes example headers in the DocSite to improve clarity, readability, and consistency.

Problem
Some example titles were:

• Inconsistent header casing across examples (mix of Title Case and sentence case).
• Non-uniform terminology and phrasing reduced clarity.
• Unclear headers

Changes

• Updated example headers across the docs site to use consistent Title Case and clearer phrasing.
• Updated Example headers for more readability
• No functional changes

Contribution checklist

• I have followed the contributing guidelines.
• I have formatted my code with Prettier and checked for linting issues with ESLint for code readability.
