update ci sync all group test

[minhsaco99]

Description

Update CI test workflow to use uv sync --all-groups instead of manually specifying
each dependency group. This ensures all groups defined in pyproject.toml are
automatically included when running tests, making it easier to maintain as new groups
are added.
