ensure toolkit is using external cargo command (#13943)

# Description

@cptpiepmatz and I ran into a problem where `toolkit check pr` and
`toolkit clippy --verbose` wouldn't work. I tracked it down to me using
`cargo-completions.nu` out of the nu_scripts repo. It was redefining
`cargo clippy`. The fix was to ensure that all `cargo` commands in
`toolkit.nu` use the external `^cargo`.

Specifically, the problem with `cargo clippy` in `cargo-completions.nu`
is it didn't seem to allow `-- -D blah` type parameters.

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

# 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
> ```

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
