fix: Update Logo import path in Header component

The commit updates the import path for the Logo component in the Header component. The previous import path was incorrect and has been corrected to "./assets/holysheets-logo.svg". This ensures that the correct logo is displayed in the header.

Refactoring the import path improves the maintainability and readability of the codebase.
