return in reduce command closure (#7961)
# Description

Fix for #7933. I've read through code and found the obvious difference
between them, where `each` command calls eval_with_early_return
e89e734ca2/crates/nu-command/src/filters/each.rs (L158),
while `reduce` command uses eval_block
e89e734ca2/crates/nu-command/src/filters/reduce.rs (L143)

That simple change seems to resolve the problem. 

# User-Facing Changes

Allows the use of `return` in reduce closures, as per example in #7933
description. Arguably it's restoring consistency, than changing user
interface.

```
[1, 2] | reduce --fold null { |it, state|                                                           
::: if $it == 1 {
:::     return 10
::: }
::: return ($it * $state)
::: }
20
```

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

    

- [x] `cargo fmt --all -- --check` to check standard code formatting
(cargo fmt --all applies these changes)
- [x] `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- [x]  `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.
