Remove "How do you host your website on Google App Engine?" page

[Josh-Cena]

This doc is terribly out of date (the sample site doesn't work) and it doesn't really say much beyond the official docs, so just deleting and redirecting to the official docs. There are better vendors to recommend.

Fixes #36875

Fly-by - don't you have to remove from the learn sidebar too?

FWIW Deletion much appreciated.

[Josh-Cena]

Tools_and_setup automatically lists all of its subpages, so no update is needed.

Awesome. Thank you.
