Reorganize the README files, move them from the root folder to docs sub-folder

[marcomarchesi]

Hi everyone, I finally started looking at Eliza code as I would love to contribute as much as I can.

First thing I noticed is that all the README files in various languages are in the root folder, making an unnecessary long scrolling. Also the files are not consistent each other, they contain different documentation. From a first overview it looks a bit confusing.

I would suggest to move all the README files (except the EN one) into a subfolder readme or under docs, with each one still linked in the root README, to make the root folder cleaner.

About the consistency, I still need to see how documents are generated but AI-based translation (by an Eliza agent?) could be a good option, unless you already encountered issues on having that.
