EditorInspectorPlugin can't hide some array fields

### Tested versions

- Producible in: 4.4
- other versions not tested

### System information

Godot v4.4.stable (32702e496) - Windows 10 (build 19045) - Multi-window, 1 monitor - OpenGL ES 3/ANGLE (Compatibility) - Intel(R) HD Graphics 520 (Intel Corporation; 30.0.101.1338) - Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz (4 threads)

### Issue description

I wanted to write an addon to hide the `Size:` and `> Resource` fields in exported arrays. This is specially useful in nested arrays of resources, otherwise it would turn into a mess real fast. But not only there's no way to access `Size:`, you can't even hide the groups in `_parse_group`. Test addon (inspector plugin):
```gdscript
@tool
extends EditorInspectorPlugin

func _can_handle(object: Object) -> bool:
return true

func _parse_property(object, type, name, hint_type, hint_string, usage_flags, wide) -> bool:
prints('_parse_property', object, type, name, hint_type, hint_string, usage_flags, wide)
return false

func _parse_group(object: Object, group: String):
prints('_parse_group', object, group)
if group == 'Resource':
return true
return false

func _parse_category(object: Object, category: String) -> void:
prints('_parse_category', object, category)
```
The result doesn't include `Size` at all, as it's not a property, a group or a category. It also doesn't show `> Resource`. It just shows the children of that which is useless for this case.

The second image is shown upon opening the `Nested Res` property.

### Steps to reproduce

- open the MRP
- open the main scene (root node selected)
- in the inspector, when you open/close the resources, things will be printed. There you can see what I mean

### Minimal reproduction project (MRP)

Open the linked minimal reproduction project and run the main scene with the root node selected. Start by tracing the EditorInspectorPlugin callbacks shown in the issue, especially _parse_property and _parse_group, and compare the handling of nested resource arrays. Done means the plugin can hide the array Size field and the Resource group, including when nested.
