HyukjinKwon opened a new pull request, #57185: URL: https://github.com/apache/spark/pull/57185
### What changes were proposed in this pull request? This documents, for every built-in function in the PySpark `functions` API (`builtin.py`), the accepted input type of each argument (`Parameters`) and the return type of each function (`Returns`), using the numeric umbrella where numeric subtypes cast in and `timestamp` for TIMESTAMP_NTZ in type phrases. Subtask of SPARK-57999, split out from apache/spark#57079 for reviewability. This PR covers only the PySpark `builtin.py` surface. ### Why are the changes needed? The PySpark `functions` docstrings previously had no per-argument type information for most functions. This fills that gap. ### Does this PR introduce _any_ user-facing change? Yes, documentation only. No behavioral or API change. ### How was this patch tested? Python lint (flake8 + black) and the docstring doctests pass. Types were derived from and verified against the analyzer's behavior and each expression's `inputTypes` / `dataType`.
