• devtools-guide-chromium
• devtools-protocol-chromium - 1 article (w/ outdated Note per below); can include in other PR.
• extensions-chromium
• progressive-web-apps-chromium
• webdriver-chromium

This PR contains a good rewrite to retain, replacing the outdated Note in
https://learn.microsoft.com/en-us/microsoft-edge/devtools-protocol-chromium/
by two paragraphs written from 2024 POV:

Microsoft Edge uses the Chromium browser engine.  The Microsoft Edge DevTools Protocol matches the APIs 
of the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/) (CDP).
 
The [Microsoft Edge (EdgeHTML) DevTools Protocol](/archive/microsoft-edge/legacy/developer/devtools-protocol/index) 
is legacy and won't be updated.  Any methods that were prefixed with `ms` in the Microsoft Edge (EdgeHTML) 
DevTools Protocol are no longer supported in the Microsoft Edge DevTools Protocol.
