Chore: hoist example projects for discoverability (#2959)

* hoist example projects, remove oidc

* move over example projects from the separate repo

* Update ecommerce site to the latest version of dioxus

* update wifi scanner to 0.5

* drop the chatbot example; might be restored in a separate PR
