refactor: standardize string quotes to double quotes in errors.ts

- Changed all string literals from single quotes to double quotes for consistency
- Reformatted multi-line strings and function parameters for improved readability
- Updated headers and console logs accordingly to match the new quote style

This ensures adherence to project coding standards and enhances code maintainability.
