shortcut_context cannot be set from editor.

[Lielay9]

Godot version

v4.0.beta1.official [20d6672]

System information

Windows 10, Vulkan, Nvidia 1050TI

Issue description

Title. The property is exposed to the editor but cannot be set.

If this is intended, the property shouldn't probably be exposed.

Maybe it should use the same interface as exported nodes and nodepaths?

Steps to reproduce

1. Create a button-node
2. Try to set shortcut_context
3. Observe that it doesn't work
