Code Review

This pull request addresses an issue with the pip upgrade command in the CI script by removing the --break-system-packages flag. This change appears to be a valid fix, likely because the version of pip being upgraded from does not support this flag. To improve future maintainability, I've suggested adding a comment to explain why this flag is omitted for this specific command while being used elsewhere in the script.

[gemini-code-assist]

For better maintainability, it would be helpful to add a comment explaining why --break-system-packages is omitted for this specific pip command, while it's used for subsequent ones. This is likely because the pre-upgrade pip version might not support this flag, and adding this context will help future contributors understand the reasoning.

Suggested change

	pip install --upgrade pip
	# --break-system-packages is omitted here as the initial pip version might not support it.
	pip install --upgrade pip
