Subject: [PATCH] remove an unused import in release (#5320)

# Objective

- There is a warning when building in release:
```
warning: unused import: `Local`
 --> crates/bevy_render/src/extract_resource.rs:4:34
  |
4 | use bevy_ecs::system::{Commands, Local, Res, ResMut, Resource};
  |                                  ^^^^^
  |
  = note: `#[warn(unused_imports)]` on by default
```
- It's used https://github.com/bevyengine/bevy/blob/814f8d1635587ad26d9e1e6e08e7d63b4355f4d7/crates/bevy_render/src/extract_resource.rs#L45
- Fix it

## Solution

- Gate the import
