[SPARK-44524][BUILD] Balancing pyspark-pandas-connect and pyspark-pandas-slow-connect GA testing time

### What changes were proposed in this pull request?
The pr aims to balancing `pyspark-pandas-connect` and `pyspark-pandas-slow-connect` GA testing time.

### Why are the changes needed?
After pr: #42146, the difference in testing time between `pyspark-pandas-connect` and `pyspark-pandas-slow-connect` is a bit significant, which affects the overall running time. In order to make GA operation more efficient and stable.

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
- Pass GA.
- Manually monitor GA.

Closes #42115 from panbingkun/free_disk_space.
