It is needed to migrate whenever it is possible builtin UDF documentation from code based to attribute based.

Function list can be found in SessionStateDefaults::default_scalar_functions()

Example can be found https://github.com/apache/datafusion/pull/13646/files#diff-1528bf73810e3fb12fd1d4e76a8b46acb650549ef37d3c131464e087f97ca515L25

The translation can be done manually or in semi automatic way, uncommenting a function in PR #13669 locally. This will generate local text files with attribute text which can be copy pasted to structs. However its still needed to remove code based documentation manually, add imports, etc

Please refer to PR #13646 which completed the migration for aggregation functions
