Clean up the examples readme (#22419)

A few changes:

* Remove the search tip (it relies on searching for the new keyword which we no longer use)
* Remove mentioning of examples that are either stale or only used for internal purposes (such as test)
* Cross-link to the samples repo

**Tip:** To see examples of how to use a specific Flutter framework class,
copy and paste a URL with this format in your browser. Replace `foo` with the
classname you are searching for (for example, here's the
[query](https://github.com/flutter/flutter/search?q=path%3Aexamples+new+AppBar)
for examples of the
[`AppBar`](https://docs.flutter.io/flutter/material/AppBar-class.html) class).

Available examples include:
- **Hello, world** The [hello world app](hello_world) is a basic app that shows
the text "hello, world."
- **Hello, world** The [hello world app](hello_world) is a minimal Flutter app
that shows the text "hello, world."
- **Flutter gallery** The [flutter gallery app](flutter_gallery) showcases
Flutter's widgets, including its implementation of
[material design](https://material.google.com/).
- **Platform Channel** The [platform channel app](platform_channel)
demonstrates how to connect a Flutter app to platform-specific APIs. For

Android version.
## Notes
Note on Gradle wrapper files in `.gitignore`:
Gradle wrapper files should normally be checked into source control.
The example projects don't do that to avoid having several copies of the
wrapper binary in the Flutter repo. Instead, the Gradle wrapper is
injected by Flutter tooling, and the wrapper files are .gitignore'd to
avoid making the Flutter repository dirty as a side effect of running
the examples.
