Code Review

This pull request refactors the Divider component defaults to be generated from the Material Design token database. It introduces a new 'DividerTemplateM3' to handle the generation of 'DividerThemeData' defaults, updates the generator tool to include this template, and adds corresponding unit tests to verify the generated output. The manual implementation of '_DividerDefaultsM3' in 'divider.dart' has been removed in favor of the generated part file. I have no feedback to provide as there were no review comments.
