Fix multi-line redirection inside a block (#7808)

# Description

Fixes: #7786

The issue is because the lite block is wrong while converting from lex
tokens

# What happened internally?
Take the following as example:
```
❯ def foobar [] { 
    'hello' out> /tmp/output.1
    'world' out> /tmp/output.2
}
```

## Before:
```
LiteBlock { block: [
    LitePipeline { commands: [
        Command(None, LiteCommand { comments: [], parts: [Span { start: 40900, end:40907 }] }),
        Redirection(Span { start: 40908, end: 40912 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40913, end: 40926 }] })]
    },
    LitePipeline { commands: [
        Redirection(Span { start: 40908, end: 40912 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40929, end: 40936 }] }),   // this is wrong, should be command.
        Redirection(Span { start: 40937, end: 40941 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40942, end: 40955 }] })]
    }] }
```

## After:
```
LiteBlock { block: [
    LitePipeline { commands: [
        Command(None, LiteCommand { comments: [], parts: [Span { start: 40824, end: 40831 }] }),
        Redirection(Span { start: 40832, end: 40836 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40837, end: 40850 }] })] 
    },
    LitePipeline { commands: [
        Command(None, LiteCommand { comments: [], parts: [Span { start: 40854, end: 40861 }] }), 
        Redirection(Span { start: 40862, end: 40866 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40867, end: 40880 }] })] 
    }
] }
```

# 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

# 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.
