a refactoring idea to rewrite the `README`

hello there 👋 😋

i feel this website repository is mainly made for developers or people who click on the "Edit this page on GitHub" button in the footer.

the other day i was looking for contribution guidelines and ended up asking how to run the website locally on the discord...
i did not see the CONTRIBUTING.md file in the root of the repo 😭

in fact, i looked at the main README, looking for instructions but found none => this is because the main ./README.md file IS the
english frontpage of www.nushell.sh!

my idea

i propose to move the frontpage of the website to some other place than ./README.md and write a true development-oriented README.md
to:

• point to the website itself at www.nushell.sh
• point to the main nushell repo
• explain in details how to contribute to this repo OR at least explicitely point to CONTRIBUTING.md

some details

• i think the paths to all the pages MD files are specified in .vuepress/configs/, right?
• i propose to move blog/, book/, commands/, contributor-book/ and cookbook/ to a new en/ directory, leading to the following architecture:

.
├── CNAME
├── CONTRIBUTING.md
├── i18n-meta.json
├── i18n.nu
├── LICENSE
├── make_docs.nu
├── package.json
├── package-lock.json
├── README.md
├── assets/
├── de/
├── es/
├── en/
├── ja/
├── pt-BR/
├── snippets/
├── tr/
└── zh-CN/

and one more level details

.
├── CNAME
├── CONTRIBUTING.md
├── i18n-meta.json
├── i18n.nu
├── LICENSE
├── make_docs.nu
├── package.json
├── package-lock.json
├── README.md
├── assets

├── de
│   ├── README.md
│   └── book
├── es
│   ├── README.md
│   ├── book
│   └── contributor-book
├── en
│   ├── blog
│   ├── book
│   ├── commands
│   ├── contributor-book
│   └── cookbook
├── ja
│   ├── README.md
│   └── book
├── pt-BR
│   ├── README.md
│   ├── book
│   └── contributor-book
├── snippets
│   ├── installation
│   ├── introduction
│   └── moving_around
├── tr
│   ├── README.md
│   └── book
└── zh-CN
    ├── README.md
    └── book

that way

• the english default channel would be just another language channel, even though the prefered one by default
• the repo would have a more homogenous structure
• we would be able to move the english frontpage from README.md to en/README.md, as with the other languages
• we would be able to write a true README for the website repo

i wanted to have some feedback before trying to refactor the website like this.
shouldn't be that much work, mainly changing paths, but ehe 😉

Beginne mit README.md, CONTRIBUTING.md und den Pfaddefinitionen in .vuepress/configs/. Prüfe, wie blog/, book/, commands/, contributor-book/, cookbook/ und die Sprachverzeichnisse referenziert werden, bevor du den Umzug vorschlägst. Als abgeschlossen gilt die Aufgabe, wenn das Repository über eine entwicklungsorientierte README verfügt, der englische Inhalt unter en/ liegt und alle dokumentierten Pfade konsistent bleiben.
