This PR creates a main example to appear on pub at https://pub.dev/packages/material_ui/example. It is simply a list of buttons that open some of our existing examples that might be useful for someone that's new to the package.

## How to review

Most files were generated by running `flutter create .` inside the example/ directory (to make it a runnable example). The only files you really need to review are:

 * example/lib/main.dart
 * example/test/widget_test.dart

Follow up to #12061, #12119

Port over the remaining `time_picker_test` cases from flutter/flutter#184279 that were initially excluded in #12061 due to lack of localization support in `material_ui`.

Work towards flutter/flutter#182636 and flutter/flutter#188395

## Pre-Review Checklist

**Note**: The Flutter team is currently trialing the use of [Gemini Code Assist for GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code). Comments from the `gemini-code-assist` bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.

[^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.
