Create AsciiDoc WG Website

I made the initial commit for this project. I did my best to include variations of the different things you can do with our template.

For example, I added a menu, sidebar menu, and dropdown menus in https://github.com/EclipseFdn/asciidoc.eclipse.org/blob/main/config.toml

The content of the main branch is available via https://eclipsefdn-asciidoc.netlify.app/. However, the plan would be to host the site on EF infra under asciidoc.eclipse.org.
