generate: switch the position of <initial> and <closure>, so the closure can have default parameters (#13393) ...

# Description
Close: #12083 
Close: #12084 

# User-Facing Changes
It's a breaking change because we have switched the position of
`<initial>` and `<closure>`, after the change, initial value will be
optional. So it's possible to do something like this:

```nushell
> let f = {|fib = [0, 1]| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} }
> generate $f | first 5
╭───┬───╮
│ 0 │ 0 │
│ 1 │ 1 │
│ 2 │ 1 │
│ 3 │ 2 │
│ 4 │ 3 │
╰───┴───╯
```

It will also raise error if user don't give initial value, and the
closure don't have default parameter.
```nushell
❯ let f = {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} }
❯ generate $f
Error:   × The initial value is missing
   ╭─[entry #5:1:1]
 1 │ generate $f
   · ────┬───
   ·     ╰── Missing intial value
   ╰────
  help: Provide <initial> value in generate, or assigning default value to closure parameter

```

# Tests + Formatting
Added some test cases.
