marienz 7ce66a9b77 Also type-check optional arguments (#16194 )

# Description
Type-check all closure arguments, not just required arguments.

Not doing so looks like an oversight.

# User-Facing Changes

Previously, passing an argument of the wrong type to a closure would
fail if the argument is required, but be accepted (ignoring the type
annotation) if the argument is optional:

```
> do {|x: string| $x} 4
Error: nu:🐚:cant_convert

  × Can't convert to string.
   ╭─[entry #13:1:21]
 1 │ do {|x: string| $x} 4
   ·                     ┬
   ·                     ╰── can't convert int to string
   ╰────
> do {|x?: string| $x} 4
4
> do {|x?: string| $x} 4 | describe
int
```

It now fails the same way in both cases.

# Tests + Formatting
Added tests, the existing tests still pass.

Please let me know if I added the wrong type of test or added them in
the wrong place (I didn't spot similar tests in the nu-cmd-lang crate,
so I put them next to the most-related existing tests I could find...

# After Submitting
I think this is minor enough it doesn't need a doc update, but please
point me in the right direction if not.
