feat: revamp iteration one

[seiyan-writer]

What is the purpose of the change?

Introduces the first iteration of the docs revamp.

Describe the changes to the documentation

This update introduces a top bar navigation system to organize and segment the docs more effectively with some broad improvements to the docs themselves, along with a landing page. The top bar helps improve navigation and access to key docs categories. This implementation builds on earlier sidebar ideation and categorization efforts, with the goal of simplifying navigation and enhancing user experience.

The proposed top bar categories (for today) are: "Learn", "Build", "Operate", "Reference", and "Providers" (which is intentionally kept top level for visibility). Different categories were considered, as seen in the associated PRs.

The sub docs are the first step in a larger revamp of the Sei docs. There are different components that will also be introduced in separate updates as fast follows to this initial PR, meant to introduce more a more dynamic and targeted learning experience, along with updates to a various individual docs.

The next phases will involve refining the content within each section, gradually restructuring and adding new material as needed.

It captures the settled on updates (and experimentation) in:

• feat: new docs structure (1/n) #146
• feat: new docs structure (2/n) #164
• feat: new docs structure (3/n)  #168
• feat: new docs structure (4/n) #169
• feat: new docs structure (5/n) #172
• Feat/docs revamp components #182
• feat: new docs structure (6/n) #186
• feat: new docs structure (7/n)  #198

NEW:

• Incorporates initial landing page
• Revamps Ecosystem Providers homepage

Additional To-dos

• Settle on frontend methodology / framework and refactor components (right now there is a mix of different approaches for components and styling)
• Address general docs feedback
