itholic 28a201a442 [SPARK-35873][PYTHON] Cleanup the version logic from the pandas API on Spark
### What changes were proposed in this pull request?

This PR proposes removing the legacy Koalas version from pandas API on Spark package.

And also remove the Python version check logic since now pandas-on-Spark should follow the PySpark's Python version.

### Why are the changes needed?

Since Koalas is ported into PySpark, we don't need to keep the version logic for Koalas.

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

Now the legacy Koalas user should follow the version from PySpark.

### How was this patch tested?

Manually built the package and see it's successfully done.

Closes #33128 from itholic/SPARK-35873.
