This PR fixes a corner case of goto definition in lsp server.
```nushell
let foo = 1
match $foo {
_ if $foo == 1 => 1
# |_______________ goto definition does not work here
_ => 2
}
```
Since `match_pattern.guard` is not handled in this function (which could
be another issue).
23dc1b600a/crates/nu-parser/src/flatten.rs (L604-L658)
In this PR, however, finding leaf expression at the cursor is done with
the new AST traversing helper functions.
Theoretically, this is faster as the flattening and filtering are
combined in a single scan; the difference could be negligible though.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
# 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` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` 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
> ```

3 new test cases added, will add more if new issues found.
# After Submitting
<!-- If your PR had any user-facing changes, update [the
