Docs Improvement

I followed the tutorial and it uses classes however some widget's don't have class examples

so for example I got error

Traceback (most recent call last):
  File "E:\experience-impact\JMPModelGUI.py", line 124, in <module>
    app = App()
  File "E:\experience-impact\JMPModelGUI.py", line 120, in __init__
    self.my_frame = ModelFrame(master=self)
  File "E:\experience-impact\JMPModelGUI.py", line 106, in __init__
    self.label = ctk.CTkLabel(text="OpenVessel Models")
TypeError: __init__() missing 1 required positional argument: 'master'

I didn't know that ctkCTkLabel needed master=self to pass it as a app object?

class ModelFrame(ctk.CTkFrame):
    def __init__(self, master, **kwargs):
        super().__init__(master, **kwargs)
        # self.CTkLabel( text="OpenVessel  JMP Models", font=('Helvetica', 18, 'bold')).grid(row=0, column=0, padx=20, pady=20, sticky="nsew"
        # add widgets onto the frame, for example:
        self.label = ctk.CTkLabel(master=self, text="OpenVessel JMP Models")
        self.label.grid(row=0, column=0, padx=20)

if there is update to the docs for class examples it could lessen confusion for users

Start by locating the tutorial's widget examples and compare the existing usage with the class-based example in the issue. Update the documentation to show class examples where needed, including how the widget receives its master; done when users can follow the tutorial without encountering the reported missing-master error.
