docs: Default Splash / Loading screen for web app in index.html (#177084)
Contributes to #102178

First I wanted to cherry-pick
https://github.com/flutter/gallery/pull/630. But then I noticed that
there already exists a documentation:
https://docs.flutter.dev/platform-integration/web/initialization.
As most users won't expect this to be customizable (as myself), I wrote
a little docs in the index.html.tmpl that link to this page.

https://docs.flutter.dev/platform-integration/web/initialization#example-display-a-progress-indicator

I still think a default splash screen should be in place, e.g. by
providing the `flutter_bootstrap.js` by default (?)
