* Some changes ported from the work on the makerkit.dev website related to the marketing sections of the kit, such as documentation
* Added slight background hue to make darker theme better looking
* Support more complex configurations for documentation navigations.
* Do not fetch content from Keystatic when non-needed
* Add cursor pointers in dropdown
* Updated packages
* Add Analytics package
Created a new analytics package with a manager to handle tracking of events and page views. The package includes a default provider that can be switched out and uses a NullAnalyticsService if no provider is registered. Additional types, scripts, and package configuration are also provided to support development.
* Add marketing components for UI package
Introduced new React components under "marketing" for the UI package. These include 'Pill', 'GradientSecondaryText', 'Hero', 'CtaButton', 'FeatureCard', 'FeatureGrid', 'FeatureShowcase', 'GradientText', 'Header', and 'SecondaryHero'. Updated 'package.json' to export these components. Replaced the implementation of 'Home', 'SiteHeader', and 'SiteFooter' with these components for cleaner code and better reusability.
