Before this PR, you can access rendered error values that are raised in
a `try/catch` block by accessing the `rendered` element of the catch
error value:
```
$ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered }
my cool error:
nu:🐚:directory_not_found

  × Directory not found
  help: /home/rose/nonexist.txt does not exist
```

However, the rendered errors don't include the labels present in the
real rendered error, which would look like this:
```
$ ls nonexist.txt
Error: nu:🐚:directory_not_found

  × Directory not found
   ╭─[entry #46:1:4]
 1 │ ls nonexist.txt
   ·    ──────┬─────
   ·          ╰── directory not found
   ╰────
  help: /home/rose/nonexist.txt does not exist
```

After this PR, the rendered error includes the labels:

```
$ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered }
my cool error:
Error: nu:🐚:directory_not_found

  × Directory not found
   ╭─[entry #4:1:10]
 1 │ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered }
   ·          ──────┬─────
   ·                ╰── directory not found
   ╰────
  help: /home/rose/nonexist.txt does not exist
```

This change is accomplished by using the standard error formatting code
to render an error. This respects the error theme as before without any
extra scaffolding, but it means that e.g., the terminal size is also
respected. I think this is fine because the way the error is rendered
already changed based on config, and I think that a "rendered" error
should give back _exactly_ what would be shown to the user anyway.

@fdncred, let me know if you have any concerns with the way this is
handled since you were the one who implemented this feature in the first
place.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

The `rendered` element of the `try`/`catch` error record now includes
labels in the error output.

# 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` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` 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
> ```

- 🟢 `toolkit fmt`

# After Submitting
<!-- If your PR had any user-facing changes, update [the

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.
