Pull Request Overview

This PR updates the pygments dependency to version 2.20.0. According to Codacy, the changes are up to standards with no new quality issues detected.

The primary concern with this update is that Pygments 2.20.0 has dropped support for Python 3.8. If this project is currently running on Python 3.8, this update will lead to environment compatibility issues. It is recommended to verify the target Python version before merging.

About this PR

• Pygments 2.20.0 has dropped support for Python 3.8. Ensure that the project's execution and deployment environments are using Python 3.9 or higher to prevent compatibility issues.

Test suggestions

• Verify that the markdown rendering pipeline still functions correctly with the updated version of Pygments.
• Verify that the project's Python version is compatible with Pygments 2.20.0 (which dropped support for Python 3.8).

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify that the markdown rendering pipeline still functions correctly with the updated version of Pygments.
2. Verify that the project's Python version is compatible with Pygments 2.20.0 (which dropped support for Python 3.8).
