feat: v5 style overhaul (#2469)
Style updates:

- New "core" theme serves as base for all other themes (official and third-party)
- New CSS custom properties for simplified customization of "core" theme
  **Note:** List of available properties will be made available in documentation by embedding soruce CSS in docs after merge. Merge is required because embedded CSS needs to be in `main` branch. For now, see `_vars.css` and `_vars-advanced.css` for details.
- New theme "add-ons" modify core theme properties and/or add custom declarations as needed.
- New Prism.js theme support
- New configurable sidebar toggle design
- New typography defaults to system sans-serif and monospace fonts instead of relying on external web font.
- New "Core Dark" theme addon provide dark theme styles. Can optionally be applied based on operating system's light/dark setting using `@media` attribute on `<link>` element.
- New "Vue" theme addon. Closely replicated popular v4 theme while allowing for v5 enhancements.
- New CSS class names available for adding loading indicators, adding sidebar expand/collapse icons, adding sidebar group styles, clamping sidebar links to a single line with ellipses, and changing the sidebar toggle icon.
- New auto-generated gradient background for cover page (ensure gradient hue is > 50 degree apart, use OKLCH color if supported, randomize grandient angle, reduce brightness in dark mode)
- New button styles (basic, primary, secondary)
- New form element styles (text input, radio, checkbox, )
- New "callouts" (previously "important" and "tip" helpers)
- New default syntax highlighting theme (from [docsify-themeable](https://jhildenbiddle.github.io/docsify-themeable/))
- New auto-generated theme color shade and tint colors
- New auto-generated monochromatic color palette
- New form element styles (fields, legend, text input, text area, checkbox, radio, toggles, and select)
- New "headerless" tables
- New `kbd` styles
- New task list style
- New merged navbar styles (consistent with sidebar nav styles)
- New search plugin styles and keyboard shortcut indicators
- Add ability restore previously focused content element after hiding sidebar
- Add "focus trap" when sidebar is visible on mobile (accessibility)
- Add ability for sidebar links to wrap by default (previous single-line w/ ellipsis display available as CSS class on `<body>` option)
- Add sidebar `page-link`, `group`, and `group-title` CSS classes to sidebar markup.
- Add reduced motion media query to set all animation/transition timings to zero
- Update Google Font imports (use new variable vs older fixed width fonts)
- Update primary/secondary button order on coverpage (primary should be first)
- Fix missing merged navbar when loading at desktop resolution then resizing to mobile
- Fix inverted open/close sidebar visibility state at desktop/mobile resolutions
- Fix overflow setting to prevent clipping of element focus ring
- Fix safe area inset margins on mobile in landscape orientation
- Fix inverted "tip" and "warn" class names
- Fix scroll padding to prevent headers from touching top edge of viewport when scrolled to

- Move "Edit Page" link to footer
- Remove [docsify-themeable](https://jhildenbiddle.github.io/docsify-themeable/) endorsement (currently not compatible with v5 and future is unknown)

Miscellaneous updates:

- Add PostCSS config file

# Doc helper
docsify extends Markdown syntax to make your documents more readable.
> Note: For the special code syntax cases, it's better to put them within code backticks to avoid any conflict from configurations or emojis.
## Callouts
### Important content
Important content like:
```markdown
!> **Time** is money, my friend!
```
is rendered as:
!> **Time** is money, my friend!
### Tips
General tips like:
```markdown
?> _TODO_ unit test
```
are rendered as:
?> _TODO_ unit test
## Link attributes
### disabled
```md
[link](/demo ':disabled')
```
### href
Sometimes we will use some other relative path for the link, and we have to tell docsify that we don't need to compile this link. For example:
```md
[link](/demo/)
```
It will be compiled to `<a href="/#/demo/">link</a>` and will load `/demo/README.md`. Maybe you want to jump to `/demo/index.html`.
Now you can do that
```md
[link](/demo/ ':ignore')
```
You will get `<a href="/demo/">link</a>`html. Do not worry, you can still set the title for the link.
```md
[link](/demo/ ':ignore title')
<a href="/demo/" title="title">link</a>
```
### target
```md
[link](/demo ':target=_blank')
[link](/demo2 ':target=_self')
```
## Task lists
```md
- [ ] foo
- bar
- [x] baz
- [] bam <~ not working
- [ ] bim

## Markdown + HTML
You need to insert a space between the html and markdown content.
This is useful for rendering markdown content in the details element.
```markdown
<details>

- Abc
- Abc
</details>
```
