Issue description

Hi, I follow this sample (#46721) in Godot 4 and it returns an error message:

Invalid set index 'custom_punctuation' (on base: 'TextParagraph') with value of type 'String'.

I also check the document and it also says custom_punctuation is a string property.

Steps to reproduce

Create a TextParagraph object and assign a string to its custom_punctuation property.
Running the game and will return the error message.

Is this problem be fixed in Godot 4.0.dev (ed02b8a)? I rebuild Godot at this commit and seems working fine now.
