allow range as a input_output_type on filter (#9707)

# Description

This PR allows `Type::Range` on the `filter` command so you can do
things like this:
```nushell
❯ 9..17 | filter {|el| $el mod 2 != 0}
╭───┬────╮
│ 0 │  9 │
│ 1 │ 11 │
│ 2 │ 13 │
│ 3 │ 15 │
│ 4 │ 17 │
╰───┴────╯
```

# 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
