HyukjinKwon opened a new pull request, #57183: URL: https://github.com/apache/spark/pull/57183
### What changes were proposed in this pull request? This documents, for every built-in function argument, which input types it accepts, in the SQL `@ExpressionDescription` `arguments` blocks (rendered on the SQL functions reference page), using a numeric umbrella (`a numeric` / `a numeric or interval`) 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 SQL surface. ### Why are the changes needed? The SQL function reference previously had no per-argument type information for most built-in 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? Existing `ExpressionInfoSuite` and the SPARK-32870 argument-block-format tests pass. Types were derived from and verified against the analyzer's accept/reject behavior and each expression's `inputTypes` / `checkInputDataTypes`.
