Why the need of layout_builder_reorder_module_implements_alter?

Hello,

As currently the reorder links are wrapped into a container:

$sections[$key]['rearrange'] = [
            '#type' => 'container',
          ];

The hook has currently no impact so it can be removed.

I think to open another branch to get rid of this container wrapper.

If the reorder links needs to appear last (which I agree is better), then setting a weight on it will do it properly.

Ok, the problem is that "layout-builder__section" key does not have a weight. So if putting weight on links it appears after the section.

✨ Allow changing the layout of an existing section in Layout Builder UI Needs work is also proposing to put links into a dedicated container so that no side effect on other stuff.

I would prefer to not act on the links so themers can alter LB element to do their own reordering. Especially if a lot of other patches on core and other contrib modules are present.

This is very side effect prone.
