[Docs] Examples idea

[benjamincanac]

An initiative was made in #4834 to create a "Blocks" or "Examples" section with real-life use-cases of Nuxt UI components but we still have to make the actual examples.

I could see in this page examples that doesn't fit inside specific component pages or components that are too custom to be built-in in Nuxt UI like:

• Auth pages with AuthForm
• Linear Filters feat: add Filters component #5434
• Event Calendar Event Calendar Component #5533

Feel free to comment if you have some ideas.
