Issue description

The value of TextEdit.placeholder_text is not automatically resolved as a translation key. This behavior is unexpected as the LineEdit does translate the placeholder.

The attached screenshot shows a LineEdit and a TextEdit, each with msg_placeholder as their placeholder_text. The LineEdit translates it, the TextEdit does not.

Steps to reproduce

1. Add a translation file to the project
2. Set the placeholder_text property of a TextEdit in the inspector to a valid translation key
3. Run the scene -> the TextEdit shows the translation key instead of the translation
