Updated git status check action and allowed changes (#22)

The custom GitHub action for checking the cleanliness of the worktree has been replaced with an external one, 'pulumi/git-status-check-action@v1'. This new action allows certain files to have changes without causing the workflow to fail. The list of these allowed changes includes specific files in sdk directories across different languages.
