cdx-docs project

[prabhu]

We're seeking a technical author to collaborate with us on enhancing cdxgen documentation. Our goal is to add a dedicated chapter for each package manager and language. The documentation would help both our community and ML models, such as cdx1, better understand the principles of package managers and their ecosystems. Once we have some initial chapters completed, we can seek public or private funding to finalize and prepare it for publication and wider distribution.
