refactor: enhance Container component with as prop for better semantic markup

[rxtsel]

Refactor and Improvement of the Container Component

Summary

• Enhances the flexibility of the Container component by requiring the as prop to specify semantic HTML tags, following the recommended conventions for polymorphic components.
• Simplifies the markup structure by reducing unnecessary nesting across multiple views.
• The as prop is restricted to semantic container tags (div, section, article, etc.) to ensure consistent use aligned with the component’s role as a layout container. You can see all available tags here: https://github.com/coderdiaz-studio/cvfolio/blob/6877032ae38fb9ca1d660a5b1b859f42e776f281/src/components/Container.astro#L3
• The main tag is intentionally excluded because it is already used in the BaseLayout.astro component to wrap the entire page, preventing redundant markup.
