Subject: [PATCH] update `items` signature to allow `any` output (#9896)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Description

This PR updates the `items` command to allow `any` output. items takes a
closure so theoretically, any value type of output could be valid.

### Before
```nushell
{a: 1 b: 2} | items {|k,v| {key: $k value: $v}} | transpose
Error: nu::parser::input_type_mismatch

  × Command does not support list<string> input.

   ╰────
```

### After
```nushell
❯ {a: 1 b: 2} | items {|k,v| {key: $k value: $v}} | transpose

# 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 -- -c "use std testing; testing run-tests --path
crates/nu-std"` 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.
