Enhance header component with translation support and improve navigation links

- Imported the getTranslation function to provide localized text for the contact link in the header.
- Updated the navigation link filtering to use href instead of text, ensuring language independence.
- Adjusted the translations for the contact link to enhance accessibility and user experience.
- Refined the translations for applied skills in the i18n module for consistency.
