The init CLI should prompt for TS usage

Motivation

Currently the only way to init a site with TypeScript is to use the following command:

npx create-docusaurus@latest my-website classic --typescript

---

My suggestion is we should support these commands:

npx create-docusaurus@latest my-website classic --javascript
npx create-docusaurus@latest my-website classic --typescript

If no language is provided, the CLI should be interactive and ask the user if they want to use TypeScript.

Hello @slorber, I would like to work on this issue if nobody picked it up.

@san70sh Please send directly a PR, Docusaurus maintainers don't assign issue to people

Hey @slorber I implemented a solution for this, lets discuss about it in the pr! :D
