NthValue UDAF removed in v41 #12278
Description
Describe the bug
In v41 the nth_value expression function API got removed. This happened when min and max was converted to UDAF in #11013. This went undetected because there are no logical roundtrip plan tests for nth_value.
To Reproduce
The function is listed in v40:
https://docs.rs/datafusion/40.0.0/datafusion/functions_aggregate/expr_fn/fn.nth_value.html
The function is missing in v41:
https://docs.rs/datafusion/41.0.0/datafusion/functions_aggregate/expr_fn/fn.nth_value.html
Expected behavior
The nth_value UDAF is listed in v41 docs.
