### Godot version

v4.0.stable.official [92bee43ad]

### System information

Windows 10

### Issue description

After migrating to Godot 4, I was surprised that the camera wasn't moving, then I discovered that Camera2D Process Mode is "When Paused" by default, was this intentional? It seems strange to pause the camera when the game is unpaused and to unpause it when the game is paused.

### Steps to reproduce

N/A

	Vector<String> found_renames;

			process_gdscript_line(line, reg_container, builtin);

				found_renames.append(simple_line_formatter(current_line, old_line, line));

}
, this function should run only on all ".gd" files and also on lines in ".tscn" files which are parts of built-in Scripts.
