assistant: Allow passing module paths to `/rustdoc` command (#12536)
This PR updates the `/rustdoc` command to accept module paths in
addition to just a crate name.
This will return the docs.rs page just for that particular module.
### Examples
```
/rustdoc bevy
/rustdoc bevy::ecs
/rustdoc bevy::ecs::component
```
