Enhance README with an Interactive and Engaging Format

[yashpawar6849]

Description
The current README file provides essential information but could be more interactive and engaging. Adding visuals, interactive demos, and better structured documentation would improve onboarding for new users and contributors.

Proposed Changes
Include an overview diagram to illustrate OpenTelemetry’s architecture.
Add interactive code snippets (e.g., via GitHub CodeSpaces or Replit).
Improve the formatting with better use of headers, bullet points, and tables.
Include quick-start GIFs or videos demonstrating setup and basic usage.
Add FAQs or a troubleshooting section for common setup issues.

Benefits
Enhances user experience for developers new to OpenTelemetry.
Reduces onboarding friction and improves documentation clarity.
Makes the project more visually appealing and interactive.

Additional Context
Would love feedback on which interactive elements would be most useful. Also, if there’s an existing style guide or preferred tools for documentation updates, please share!

@yashpawar6849 when you talk about the README, you mean https://github.com/open-telemetry/opentelemetry.io/blob/main/README.md? If so, this is not the place for illustrating the architecture or providing code snippets, etc. We do this on the website itself, e.g. see https://opentelemetry.io/docs/ for an architecture diagram. Indeed we could clarify that much more on the README that people should go there for more details.

I second @svrnm's comments that our focus is on putting content and enhancing ux via the docs published on the website.
