`docs-serve` was duplicated. Also, extend the existent `docs-serve` script for `docs-github-serve`.

closes #26586, closes #26587

- Updates nodemon scripts to watch specific directories instead of ignoring several
- Split watch tasks for CSS and JS into main and docs
- Add docs-watch script to serve the docs instead of just build
- Add new start script so that instead of two tabs, one for docs-watch and one for watch, we just run npm start

see #22944 and #24620

With the current docs directory setup, I'm making too many mistakes and have to manually address path changes and directory moves on deploy. This makes for a frustrating experience developing locally and shipping releases. With this PR, we're basically back to the same setup from v3—duplicating the dist directory into our docs directory. Not the most ideal, but very straightforward for me as the release manager.

Fixes #26830

Only bundlesize is kept back for Node.js 10.x compatibility.
