Add rest and glob support to 'open' (#8506)

# Description

This adds two different features to `open`:
* The ability to pass more than one file to `open`.
* Support for using globs in the filenames

`open` will create a list stream and stream the output if there is more
than one file opened

Examples:

```
open file1.csv file2.csv file3.csv
```

```
open *.nu | where $it =~ "echo"
```

# User-Facing Changes

Multi-file and glob support in `open`. Original `open` functionality
should continue as before.

# 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` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

> **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.
