Code Review

This pull request updates the regex in the documentation generation script to match _getTizenInstance calls. A review comment points out that the new regex is too broad and could lead to incorrect matches across multiple getter definitions, suggesting a more restrictive pattern and the restoration of explanatory comments for maintainability.
