Fix bevy not exporting bevy::extract

[MonaMayrhofer]

Objective

Fixes #25488

Solution

• Export it

Testing

• Successfully compiled a local project that did not build before the change.

Additional Info

This PR does not address the fact that currently the ExtractComponent macro must be imported via bevy::render::extract_component::ExtractComponent, in downstream projects as bevy_extract_macros is not exported.

This pattern is also used just in bevy itself:

bevy/crates/bevy_anti_alias/src/fxaa/mod.rs

Lines 11 to 15 in 17e28cd

	use bevy_render::{
	camera::ExtractedCamera,
	extract_component::{ExtractComponent, ExtractComponentPlugin},
	render_resource::{
	binding_types::{sampler, texture_2d},

I am happy to also include fixes for these things in this PR if wanted, however I would need guidance on how, or if that should be solved.

as bevy_extract_macros is not exported.

This is intentional - note that bevy_render_macros isn't exported either, but the derives in it are exported via bevy_render , and so bevy_extract re-exports from bevy_extract_macros.

use bevy::extract::extract_component::ExtractComponent works too (both for derive and for manual impl).

This pattern is also used just in bevy itself:

This was intentional to reduce the diff. It's worth considering removing the re-export (probably remove internal usage, deprecate the bevy_render re-exports, then the next release cycle remove it).
