Remove --flag: bool support (#11541)
# Description
This is a follow up to: #11365

After this pr, `--flag: bool` is no longer allowed.

I think `ParseWarning::Deprecated` is useful when we want to deprecated
something at syntax level, so I just leave it there for now.

# User-Facing Changes
## Before
```
❯ def foo [--b: bool] {}
Error:   × Deprecated: --flag: bool
   ╭─[entry #15:1:1]
 1 │ def foo [--b: bool] {}
   ·               ──┬─
   ·                 ╰── `--flag: bool` is deprecated and will be removed in 0.90. Please use `--flag` instead, more info: https://www.nushell.sh/book/custom_commands.html
   ╰────
```

## After
```
❯ def foo [--b: bool] {}
Error:   × Type annotations are not allowed for boolean switches.
   ╭─[entry #2:1:1]
 1 │ def foo [--b: bool] {}
   ·               ──┬─
   ·                 ╰── Remove the `: bool` type annotation.
   ╰────
```

Nushell REPL

This directory contains the main Nushell REPL (read eval print loop) as part of the CLI portion of Nushell, which creates the nu binary itself.

Current versions of the nu binary will use the Nu argument parsing logic to parse the commandline arguments passed to nu, leaving the logic here to be a thin layer around what the core libraries.
