FIX: have consistent errors between std help and std help ... (#9101)
# Description
an example should show what happens quite clearly 😋 

> **Note**
> the ugly spanned errors you'll see below are fixed in
https://github.com/nushell/nushell/pull/9039 😌

in all cases we get
```
> std help commands does-not-exist-anywhere
Help pages from external command does-not-exist-anywhere:
No manual entry for does-not-exist-anywhere
Error:
  × std::help::command_not_found
     ╭─[help:662:1]
 662 │
 663 │     let command = ($command | str join " ")
     ·     ─┬─
     ·      ╰── command not found
 664 │
     ╰────
```
but

##  before this PR
```
> std help does-not-exist-anywhere
Help pages from external command does-not-exist-anywhere:
No manual entry for does-not-exist-anywhere
```
without any error, which makes it inconsistent with all the other `std
help` commands which give errors when not finding an item 🤔

# User-Facing Changes
more consistent errors when using `std help` and `std help commands`, as
shown above.

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the
standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
