[SPARK-34996][PYTHON] Port Koalas Series-related unit tests into PySpark

### What changes were proposed in this pull request? Now that we merged the Koalas main code into the PySpark code base (#32036), we should port the Koalas Series related unit tests to PySpark. ### Why are the changes needed? Currently, the pandas-on-Spark modules are not fully tested. We should enable the Series related unit tests first. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Enable Series-related unit tests. Closes #32117 from xinrong-databricks/port.test_series_related.
