What changes were proposed in this pull request?

This is a follow-up of the followings to skip pandas-related tests if pandas is not available.

• [SPARK-46812][SQL][PYTHON] Make mapInPandas / mapInArrow support ResourceProfile #44852
• [SPARK-46812][CONNECT][PYTHON] Make mapInPandas / mapInArrow support ResourceProfile #45232

Why are the changes needed?

pandas is an optional dependency. We had better skip it without causing failures.

To recover the PyPy 3.8 CI,
