bind() 'add' parameter Type

[rtommy]

Not every widget has the bind() function defined correctly.

Some Widgets have: def bind(self, sequence: str = None, command: Callable = None, add: Union[str, bool] = True):

While some other Widgets have: def bind(self, sequence=None, command=None, add=True):

This definition may lead to a TypeError: TypeError: Expected unicode, got bool

The recommended defintion would be: def bind(self, sequence=None, command=None, add: Union[str, bool] = True):

The impacted widgets are:

• CTkComboBox
• CtkEntry
• CtkFrame
• CtkLabel
• CtkScrollbar
