Repository transfer request, Dive into Deep Learning Julia version

**Is your feature request related to a problem? Please describe.**

I noticed Flux.jl lack [beginner tutorials](https://github.com/FluxML/fluxml.github.io/issues/107), not only for particular topics, but also zero-to-one ML textbook with Julia and Flux.jl.
So I create [Dive into Deep Learning](https://d2l.ai/index.html) Julia version in repository [D2lJulia](https://github.com/NeroBlackstone/D2lJulia/tree/master). For now, I only finished [chapter 2.1
](https://github.com/NeroBlackstone/D2lJulia/blob/master/notebooks/chapter_preliminaries/Data%20Manipulation.ipynb) .

**Describe the feature you'd like**

Would you (FluxML organization) like to receive this repo? Since I'm also a beginner in Flux and ML, so I think this task is best done with the Flux community. I'll continue to finish this work and merge the community pull request.

查看链接的 D2lJulia 仓库及其第 2.1 章 Data Manipulation notebook，以了解现有的 Julia 和 Flux 教程工作。确认 FluxML 是否希望接收并维护该仓库；完成的标准是已就转移决定和社区贡献路径达成一致。
