Generated code is breaking `cargo test` because of its doc-test contains a moved import

[Zed(Zijun) Chen]

Describe the bug

flutter_rust_bridge::frb_generated_boilerplate! contains a doc test which is breaking since > 2.0.0-dev.18.

Steps to reproduce

1. See CaviarChen@5c94600 All I did is add "lib" to crate-type so one could run cargo test.
2. run cargo test
3. you get:

running 1 test
error[E0412]: cannot find type `RustOpaque` in this scope

Looks like a bug, I will remove the doc test, but instead point to the doc, to be more consistent with all other parts of frb.
