In several areas of the code, event handlers had an unused event parameter. This change removes these unused parameters to improve the code's readability and maintainability. Specifically, the changes were made in the "Navbar.astro", "[...slug].astro", and "services.astro" components.
The 'bannerId' property has been removed from the AnnouncementBanner component as it is unneeded. This change has been reflected in both the component definition and places where the component is used, resulting in cleaner and more maintainable code.
Implemented a new Announcement Banner component on the main page. This banner features a dismiss button and is customizable with dynamic properties for title, bannerId, button Id, button title, and URL. Also, added a new SVG file for the banner's background pattern.
