* chore: add missing Vue support for Vercel builds
* refactor: move some functions and module-level state into classes as private methods and properties to start to encapsulate Docsify
Also some small tweaks:
- move initGlobalAPI out of Docsify.js to start to encapsulate Docsify
- move ajax to utils folder
- fix some type definitions and improve content in some JSDoc comments
- use concise class field syntax
- consolidate duplicate docsify-ignore comment removal code
This handles a task in [Simplify and modernize Docsify](https://github.com/docsifyjs/docsify/issues/2104), as well as works towards [Encapsulating Docsify](https://github.com/docsifyjs/docsify/issues/2135).
* chore: add prettier code format check to our lint script, and add a prettier script for manually formatting the whole code base
* chore: update issue/pr templates
* chore: apply our format to the whole code base

BREAKING: The new project layout might break in some tooling setups.
We've added an exports field to `package.json` to specify where
statements like `import ... from 'docsify'` will import from, and left
the `main` and `unpkg` fields as-is for backwards compatibility with the
global <script> import method. Most people who use a non-module
`<script>` tag to import Docsify will not notice a difference. Anyone
else who is importing Docsify into a specilized build setup using
`import` statements has a chance of being broken, so we've marked this
as BREAKING.
