[SPARK-43612][PYTHON][CONNECT][FOLLOW-UP] Copy dependent data files t…

…o data directory

### What changes were proposed in this pull request?

This PR proposes to move several data files used for PySpark artifact tests from `connector/connect/common/src/test/resources/artifact-tests`, added in apache#40368, to `data` directory.

### Why are the changes needed?

PySpark tests should better not depend on Spark's test package build. This PR decouples it.

### Does this PR introduce _any_ user-facing change?

No, dev-only.

### How was this patch tested?

CI in this PR should verify it.

Closes apache#41510 from HyukjinKwon/SPARK-43612-followup.
