URL: https://github.com/apache/arrow-datafusion/issues/6396

   ### Is your feature request related to a problem or challenge?
   
   Currently the error message for not providing the correct function arguments is not straightforward:
   ```
   ❯ select factorial(3.0);
   Error during planning: Coercion from [Float64] to the signature Uniform(1, [Int64]) failed.
   ```
   
   ### Describe the solution you'd like
   
   I like DuckDB's error message for wrong function arguments, we can adopt a similar approach to enhance the understandability of the error.
   ```
   duckdb> select factorial(3.0);
   Binder Error: No function matches the given name and argument types 'factorial(DECIMAL(2,1))'. You might need to add explicit type casts.
           Candidate functions:
           factorial(INTEGER) -> HUGEINT
   ```
   
   ### Describe alternatives you've considered
