Disable docusaurus versioning (#2391)

* refactor: merge options.md

* merge cli.md

* merge configuration.md

* merge standalone.md

* merge plugins.md

I didn't add plugin history in plugins.md because it is only a link to specific plugins. The plugin page (and ideally package.json) should specifies that it requires `@babel/core` 7.some-version to work.

* merge preset-env

Note: I have briefly mentioned that `useBuiltins: "entry"` will replace `@babel/polyfill` imports
before v7.4.0. It has been long deprecated and I don't expect anyone will refer to it.

* merge plugin-transform-spread

* merge plugin-transform-for-of

* merge plugin-transform-destructuring

* merge plugin-proposal-private-methods

* merge generator.md

* merge proposal-async-generator-functions.md

* merge docs/plugin-transform-flow-strip-types.md

* merge docs/plugin-transform-react-jsx-source.md

* merge docs/plugin-transform-react-jsx.md

* merge docs/plugin-transform-typescript.md

* merge preset-flow.md

* merge preset-react.md

* merge docs/preset-typescript.md

* merge usage.md

* merge docs/config-files.md

* merge node.md

* merge parser.md

* merge docs/plugin-minify-builtins.md

* merge docs/plugin-proposal-optional-chaining.md

* merge docs/plugin-proposal-partial-application.md

* merge plugin-proposal-unicode-property-regex.md

* merge docs/plugin-transform-runtime.md

* merge docs/v7-migration.md

* merge types.md

* merge docs/plugin-proposal-pipeline-operator.md

* merge polyfill.md

* merge template.md

* merge plugin-syntax-dynamic-import.md

* merge docs/plugin-proposal-decorators.md

* merge roadmap.md

It should have not been versioned at all.

* breaking: disable docusaurus versioning

* revert @babel/preset-env-standalone docs for reference only

* breaking: remove versioned_docs

* breaking: remove versioned_sidebars

* redirect next

* address review comments

-#### Versioned docs
-
-- `/docs` - the files in here are responsible for the "next" version at https://babeljs.io/docs/en/next.
-- `/website/versioned_docs/version-*` - these are the docs for the past versions, the latest one being the currently published version at https://babeljs.io/docs/en

-After making your changes to the markdown files in the `/docs` folder, a git hook script will suggest files from the past versions folders that you might also need to apply your changes to.

 ### Set File Extensions
 
+Added in: `v7.8.0`
+
 By default, Babel will override the extension of the transpiled file and use `.js` instead.
 
 To preserve the original file extension you can pass the `--keep-file-extension`.
