Some Widget properties do not have the correct type #4873
Description
Description of the bug
VS Code is displaying this error for at least 2 of the Widget properties, "field_name" and "rect".
Cannot assign to attribute "field_name" for class "Widget"
Expression of type "Literal['Custom Name for Field']" cannot be assigned to attribute "field_name" of class "Widget"
"Literal['Custom Name for Field']" is not assignable to "None"
The code still runs fine and both properties work. They are just showing red underlines in my IDE because they are only expecting "None" type. I am not experiencing the issue with any other properties or libraries I'm using currently.
How to reproduce the bug
This simple script shows the error. "field_name" and "rect" are both underlined, but "field_type" is not.
import pymupdf
#Create a new PDF
doc = pymupdf.open()
page = doc.new_page()
#Define a widget
wgt = pymupdf.Widget()
wgt.field_name = "Custom Name for Field"
wgt.rect = pymupdf.Rect(20, 10, 2200, 30)
wgt.field_type = 7
#Add widget
page.add_widget(wgt)
#Save pdf
doc.save("problem_example.pdf")
doc.close()
This code does work just fine, including the underlined fields. I think it is just an incorrect type hint.
