Editor suggested OS enums contain an underscore which is incorrect

[madmiraal]

Godot version

3.3.2.stable

System information

Ubuntu 21.04

Issue description

When using the functions OS.get_system_dir(), OS.get_native_handle() or OS.get_video_driver_name(), the suggested valid enum values all begin with _OS.*:

However, when using one of these, you get a Parser Error: Identifier not found: _OS error when running the project.

Steps to reproduce

In a script, type OS.get_system_dir(, OS.get_native_handle( or OS.get_video_driver_name(, and select one of the suggested values. Run the project.

Minimal reproduction project

N/A: This is an editor issue. A project is easily fixed by removing the underscore.
