docs: rewrite README from adoc to md with improvements

[codayon]

Closes: #441

@mominul, I haven't included the logo or icon yet. I think a banner would look better because the current header takes up the same height as a banner, but leaves empty space on both left and right sides.

Currently, the following sections are missing: Table of Contents, Features, and installation guides for specific distributions.

I haven't created any .bn.md files yet because I think it might over-complicate things right now. To make maintenance smoother, I believe we should focus on one language for now. Let me know your thoughts on that.

The installation shell scripts are currently placeholders, but we could actually make them functional, which would shorten the installation command/link.

We can also a few more sections like, Usage, Star History, A Comparison Table of Features, etc.

I think we should move from Hugo + mdBook to something more suitable for our needs. It can be Docusaurus, Starlight or VitePress. Which can help us to manage landing page, docs and blogs in the same repository.

Have you tried out https://www.fumadocs.dev/ ?

Not yet, but looks sleek.

Seems like Fumadocs, is mainly focused on UI and docs. It lacks features such as versioning, blogs, search, that are pre-built on something like Docusaurus.

[mominul]

@codayon Can you build a demo using Docusaurus? I think we should move this discussion into the discussions page.
