Improve and Standardize GitHub Issue Template for Better Clarity

[dimpal-yadav]

📝 Description:
The current issue template is too generic and doesn’t differentiate between bug reports, feature requests, and documentation updates. A redesigned template will provide structured guidance based on the type of issue being submitted.

💡 Expected Improvements:
Separate sections for:
🐞 Bug Report – Steps to reproduce, expected vs actual behavior, environment.
✨ Feature Request – Description, use-case, expected solution.
📚 Documentation Update – Current vs suggested documentation, links.
Clear checklists to ensure contributors provide all necessary details.
Optional screenshots, code snippets, or relevant links.
Predefined labels based on issue type for easy triaging.

✅ Benefits:
Reduces incomplete issue submissions.
Provides maintainers with all necessary context upfront.
Improves contribution experience and reduces review time.
