refactor(jupyter): use runtimelib for Jupyter structures and directory paths (#23826)

This brings in [`runtimelib`](https://github.com/runtimed/runtimed) to
use:

## Fully typed structs for Jupyter Messages

```rust
let msg = connection.read().await?;

self
  .send_iopub(
    runtimelib::Status::busy().as_child_of(msg),
  )
  .await?;
```

## Jupyter paths

Jupyter paths are implemented in Rust, allowing the Deno kernel to be
installed completely via Deno without a requirement on Python or
Jupyter. Deno users will be able to install and use the kernel with just
VS Code or other editors that support Jupyter.

```rust
pub fn status() -> Result<(), AnyError> {
  let user_data_dir = user_data_dir()?;

  let kernel_spec_dir_path = user_data_dir.join("kernels").join("deno");
  let kernel_spec_path = kernel_spec_dir_path.join("kernel.json");

  if kernel_spec_path.exists() {
    log::info!("✅ Deno kernel already installed");
    Ok(())
  } else {
    log::warn!("ℹ️ Deno kernel is not yet installed, run `deno jupyter --install` to set it up");
    Ok(())
  }
}
```
