Improve help output for scripts (#13445)
# Description
<!--
Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.

Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.
-->
Currently the parser and the documentation generation use the signature
of the command, which means that it doesn't pick up on the changed name
of the `main` block, and therefore shows the name of the command as
"main" and doesn't find the subcommands. This PR changes the
aforementioned places to use the block signature to fix these issues.
This closes #13397. Incidentally it also causes input/output types to be
shown in the help, which is kinda pointless for scripts since they don't
operate on structured data but maybe not worth the effort to remove.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
```
# example.nu
export def main [] { help main }
export def 'main sub' [] { print 'sub' }
```

# Tests
<!--
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
> ```
-->

Tests are still missing for the subcommands and the input/output types
