# Description
when writing a script, with variables you try to `ls` or `open`, you
will get a "directory not found" error but the variable won't be
expanded and you won't be able to see which one of the variable was the
issue...

this PR adds this information to the error.

# User-Facing Changes
let's define a variable
```nushell
let does_not_exist = "i_do_not_exist_in_the_current_directory"
```
### before
```nushell
> open $does_not_exist
Error: nu::shell::directory_not_found

should close nushell#10549 

# Description
this PR is twofold
- uses `to nuon --raw` in the error messages to make sure nushell#10549 is
solved and makes a difference between `"1"` and `1`
- tries to introduce slightly better errors, i.e. by putting left /
right on new lines => this should hopefully help when the values become
a bit big 😋

# User-Facing Changes

# Description
While nushell#11057 is merged, it's hard to tell the difference between
`--flag: bool` and `--flag`, and it makes user hard to read custom
commands' signature, and hard to use them correctly.

After discussion, I think we can deprecate `--flag: bool` usage, and
encourage using `--flag` instead.

# User-Facing Changes
The following code will raise warning message, but don't stop from
running.
```nushell
❯ def florb [--dry-run: bool, --another-flag] { "aaa" };  florb
Error:   × Deprecated: --flag: bool
   ╭─[entry #7:1:1]
 1 │ def florb [--dry-run: bool, --another-flag] { "aaa" };  florb
   ·                       ──┬─
   ·                         ╰── `--flag: bool` is deprecated. Please use `--flag` instead, more info: https://www.nushell.sh/book/custom_commands.html
   ╰────
