Rename Core Render Graph Labels (bevyengine#11882)

# Objective

bevyengine#10644 introduced nice "statically typed" labels that replace the old
strings. I would like to propose some changes to the names introduced:

* `SubGraph2d` -> `Core2d` and `SubGraph3d` -> `Core3d`. The names of
these graphs have been / should continue to be the "core 2d" graph not
the "sub graph 2d" graph. The crate is called `bevy_core_pipeline`, the
modules are still `core_2d` and `core_3d`, etc.
* `Labels2d` and `Labels3d`, at the very least, should not be plural to
follow naming conventions. A Label enum is not a "collection of labels",
it is a _specific_ Label. However I think `Label2d` and `Label3d` is
significantly less clear than `Node2d` and `Node3d`, so I propose those
changes here. I've done the same for `LabelsPbr` -> `NodePbr` and
`LabelsUi` -> `NodeUi`

Additionally, bevyengine#10644 accidentally made one of the Camera2dBundle
constructors use the 3D graph instead of the 2D graph. I've fixed that
here.

## Changelog

* Renamed `SubGraph2d` -> `Core2d`, `SubGraph3d` -> `Core3d`, `Labels2d`
-> `Node2d`, `Labels3d` -> `Node3d`, `LabelsUi` -> `NodeUi`, `LabelsPbr`
-> `NodePbr`
