[Docs]: Update README.md to reflect the latest backend folder structure

Documentation Section

README.md

Current Issue

The backend project structure documented in README.md is outdated. Since the backend has been updated, new directories such as input_validations and their associated files (e.g., index/initialization files) have been introduced. However, these additions are not reflected in the current project structure shown in the README, which can cause confusion for contributors and new developers.

Suggested Changes

• Update the backend folder structure in README.md to match the current project layout.
• Include the newly added input_validations directory and its relevant files.
• Verify that all other recently added folders and files are also represented accurately.
• Review the documentation periodically to keep it synchronized with the codebase.

Benefits

• Ensures the documentation accurately represents the current backend architecture.
• Makes onboarding easier for new contributors by providing an up-to-date project structure.
• Reduces confusion when navigating the repository.
• Improves overall project maintainability by keeping documentation in sync with implementation.
