Add Go Interview Practice to Community Resources #2816

Hey Echo team! 👋

I've created an interactive learning platform for Echo and thought you might be interested in it. The Gin and Fiber teams were really supportive when I did something similar for their frameworks.

The platform is at https://github.com/RezaSi/go-interview-practice and has 4 hands-on Echo challenges covering routing, middleware, validation, and authentication. Developers can practice Echo without any setup - just jump in and start coding.

Both Gin and Fiber teams added it to their community resources:

• Gin: https://gin-gonic.com/en/docs/learning-resources/
• Fiber: https://docs.gofiber.io/next/extra/learning-resources

Would you consider featuring this as a community learning resource? The Echo challenges are at:

• GitHub: https://github.com/RezaSi/go-interview-practice/tree/main/packages/echo
• Live platform: https://app.gointerview.dev/packages/echo

Happy to make any changes based on your feedback. Thanks for building such an awesome framework!
