Remove --flag: bool support (#11541)

Browse Source 
# 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.
   ╰────
```
