```
langref: improve the test_fn_reflection.zig doctest

Currently, the test_fn_reflection.zig doctest has an example of
.Fn.is_var_args.  This example can confuse the reader, since there is no
documentation about variadic functions and is_var_args is mainly used in
the compiler.

Remove the example with .Fn.is_var_args and add instead examples with
.Fn.return_type and .Fn.is_generic.

```
