Redesign WebView2 TOC & clarify article titles

[mikehoffms]

todo: Before merge, re-confirm that each article in live TOC exists in PR's rendered TOC.

Rendered articles for review:

• WebView2
  • https://review.learn.microsoft.com/microsoft-edge/webview2/?branch=pr-en-us-3124
  • Before
• toc
  • Removed abstract TOC buckets ("Fundamentals", "Advanced") and directly/immediately shows their content.
    • Removed unnecessary levels of nesting.
    • Used tech-topic TOC bucket names. Promoted the tech key words users are looking for, and a generally flatter design that reveals more articles and specific topics by default.
    • Enabled more flexible grouping/placement of the articles.
    • Eliminated top-level buckets that are low-value & abstract; promotes the high-value, keyword-based nodes that were contained in them.
    • Eliminated a UX of guessing and having to explore into the abstract TOC nodes.
    • Made maintenance/improvement easier.
  • Grouped together articles such as distribution.md & versioning.md that were spread apart between two different TOC buckets (Fundamentals & Deployment).
  • Group articles by tech topic (high-value grouping), not by some other, low-value quality such as info type or Fundamentals vs. Advanced.
    • Within a tech-topic toc bucket, basic articles are first; advanced or specialized articles are last.
    • Article's Intro helps user decide if article is relevant.
• Prerelease and Release SDKs for WebView2
  • https://review.learn.microsoft.com/microsoft-edge/webview2/concepts/versioning?branch=pr-en-us-3124
  • Before/Live
  • Changed article title from: Understand the different WebView2 SDK versions.
• Interop of native and web code
  • https://review.learn.microsoft.com/en-us/microsoft-edge/webview2/how-to/communicate-btwn-web-native?branch=pr-en-us-3124
  • Before/Live
  • Changed article title from: Interop of native-side and web-side code

Mapping from existing TOC (left) to redesigned TOC (right):

This PR 3124 replaces forked July 2023 PR #2725, which lists the irrelevant file archive.md as entirely changed by that PR, yet not at all changed by that PR.
