Duplicated examples in the main Dioxus repo

[Evan Almloff]

The Problem

There are several examples that are duplicated or remade in the main Dioxus repo:

• TODOMVC
• js framework benchmark
• file explorer

Proposed Solution

There are several advantages to having these examples in the main repo:

• CI checks the examples to insure they are correct every release
• The examples in the main repo are more discoverable
• The main repo could be a single place to get all examples

We could move all examples into the main repo and depreciate this repo.

I've addressed this issue in the following PR: DioxusLabs/dioxus#1941

Since this issue has been addressed, I would suggest depreciating this repository ahead of the 0.5 release.
