Interpolate WorldQuery path in docs of generated types (#14985)

# Objective

Fixes #14972

## Solution

Uses the `concat!` macro to interpolate the `path` variable.

## Testing

* Run `cargo doc --workspace --open`
* Check functionality of `WorldQuery` links within `NodeQueryItem`,
`NodeQueryReadOnly`, `NodeQueryReadOnlyItem` docs
