Rework help generation internals (#13531) 
Reworking some of the sprawling code we use to generate the `help cmd`
or `cmd --help` output.

This touches mainly the rendering and not the gathering of the necessary
data (see open bugs under
[label:help-system](https://github.com/nushell/nushell/issues?q=sort%3Aupdated-desc+is%3Aopen+label%3Ahelp-system))

Fixes #9076 
Fixes the syntax shape output on flags to be consistent.

## Example
```nushell
def test [
  positional: int,
  documented: float, # this has documentation
  default = 50,
  optional?,
  --a = "bla",
  --bla (-b) = "bla", # named with default
] {}
```
