* docs: add past versions to the tutorial
I changed "we" to "you" like the other sections of the tutorial.
I removed yarn from the code because `yarn version` didn't run on my Windows 10 system (see issue [1743](https://github.com/facebook/docusaurus/issues/1743)).
I added headings for the current version, next version, and past versions.
* Update tutorial-version.md
* docs: add the repository to the localhost:3000 link
Fix two links on **[Create Pages](https://docusaurus.io/docs/en/next/tutorial-create-pages)**.
* docs: use the same start command on both pages
The start command in **[Scaffold the Site](https://docusaurus.io/docs/en/next/tutorial-create-new-site)** is "Run `npm start` or `yarn start.`" It will help new users to see the same start command again. A slightly different command will make new users think that something slightly different is happening.
* docs: change the ID of the new documentation page
The page ID "doc4" is already used by one of the downloaded pages, docs/exampledoc4.md, shown below:
```
---
id: doc4
title: Other Document
---
this is another document
```
* docs: removed docusaurus-tutorial/ from the links
I think the tutorial should tell Windows users to use Git Bash. Later in the tutorial is a command that worked in Git Bash, `publish-gh-pages`, but didn't work for me at the Windows command prompt.
* docs: add an HTTPS example for publish-gh-pages
I moved step 1 to step 2 so the terminal steps would be together. I added Git Bash, because `publish-gh-pages` worked for me in Git Bash but didn't work at the Windows command prompt.
I added HTTPS to step 4 because, on my system, HTTPS worked for me but SSH didn't work. I changed <GIT_USER> to USERNAME and deleted the $ prompt, to be consistent with other examples in the tutorial.
* Update tutorial-publish-site.md
The description of `npm` fits better in the opening paragraph than in a numbered step. The note about version 8 fits better in the Check section than the Install section.
The `cd` step seems like the first step of "Install the Docusaurus init command," instead of the last step of "Create a GitHub repository and local clone."
* Add a cd step before clone in "Setting Up"
Add a `cd` step before clone in **[Setting Up](https://docusaurus.io/docs/en/next/tutorial-setup)**, add examples of `cd` in steps 5 and 7, and edit other steps.
* Update tutorial-setup.md
I wanted to enable superscript and subscripting to a v1 site. It wasn't quite clear how to do it. @yangshun helped me figure it out. So I thought I would document it.
* feat(core): use 0.0.0.0 for livereload address
