### Godot version

4.0 beta 16 and 17

### System information

Windows 11

### Issue description

Before beta 16 you could write `@export_category(name)` and it would make a category with "name" as the name.
Now you must use a string when defining the category name. (`@export_category("name")`)
The issue is that the moment you type something that doesn't start with `"` the engine crashes.

### Steps to reproduce

1. Create a script.
2. Write one of the following:
a) `@export_category()`
b) `@export_group()`
c) `@export_subgroup()`
3. In the parentheses write *any* character other than `"`.
4. Watch it crash.

If you managed to save the file the project will crash when opened.
