Move documentation repo to the monorepo

[RaananW]

Move the documentation repository to the monorepo, while keeping it built and hosted by vercel.

Apart from the advantage of centralizing all of our repositories, another advantage in moving the Docs repo to this core repository is the typedoc build which will use the sources instead of the declaration files.

Working on this task. This would add roughly 4000 new files to the monorepo, most of them binaries. I will try finding a different solution to the binary files, as I am trying to avoid a huge repository that will take long to checkout
