Short description of error
Compositor node tree .links.new does not create group input/output in Blender 3.5 beta. (This works in all previous versions of Blender).

Exact steps for others to reproduce the error

# create a new compositor node group and add its input and output nodes
scene = bpy.context.scene
scene.use_nodes = True
compositor_nodes = scene.node_tree.nodes

node_tree = bpy.data.node_groups.new('new_group', 'CompositorNodeTree')

node_group = compositor_nodes.new('CompositorNodeGroup')
node_group.node_tree = node_tree
node_group.location = (400, 500)

group_input = node_tree.nodes.new(type='NodeGroupInput')
group_input.location = (0, 30)

group_output = node_tree.nodes.new(type='NodeGroupOutput')
group_output.location = (620, 0)

# create a new image mix rgb node in the group, just as an example
mix_node = node_tree.nodes.new(type='CompositorNodeMixRGB')
mix_node.location = (350, 75)

# create links to the group input and output nodes
# NOTE: HERE IS THE BUG. The links are created, but actual input and 
# outputs are not. In previous versions of Blender, the group would now
# have a usable input and output.
node_tree.links.new(group_input.outputs[0], mix_node.inputs[1])
node_tree.links.new(mix_node.outputs.get('Image'), group_output.inputs[0])

This seems to be replicable every time, on both Mac and Windows.
