related to
- https://github.com/nushell/nushell/pull/10456

# Description
this PR will fix the public API of the standard library by removing the
type annotations from public boolean switches.

1. the signature before
```nushell
clip [--silent: bool, --no-notify: bool, --no-strip: bool, --expand (-e): bool, --codepage (-c): int]
```
2. the signature after
```nushell
clip [--silent, --no-notify, --no-strip, --expand (-e), --codepage (-c): int]
```
