[material_ui] Remove manual version changes

[justinmc]

material_ui has had publishing turned off, but we're going to turn on the batch release process soon. This PR adjusts the pubspec version and Changelog to match what's on Pub, so that the batch release process can take over from there.

The version was originally bumped manually in #11649.

This is the material_ui version of #12252.

A future PR will come after this one and will enable the batch release process.

In a follow up PR, I should make a pending changelog like this:

changelog: |
  - Copies over all Material code from flutter/flutter.
  - Copies over Material localizations from flutter/flutter's flutter_localizations package.
  - Unpins material_color_utilities.
  - Migrates API doc samples and formatting.
  - Updates minimum supported SDK version to Flutter 3.44/Dart 3.12.

version: patch

Code Review

This pull request reverts the version of the material_ui package from 0.0.2 to 0.0.1 in pubspec.yaml and CHANGELOG.md, removing the changelog entries associated with version 0.0.2. There are no review comments, and I have no feedback to provide.
