[🐛 Bug]: TypeError: WebDriver.__init__() got an unexpected keyword argument 'desired_capabilities'

[tscandalitta]

What happened?

I'm running some automation tests on a webkit based browser

Code:

from selenium.webdriver import WebKitGTK

webdriver_path: str = "/usr/bin/WebKitWebDriver"
driver = WebKitGTK(executable_path=webdriver_path)
driver.get("https://google.com")

Error:

python3.11 mytest.py 
Traceback (most recent call last):
  File "/tests/mytest.py", line 4, in <module>
    driver = WebKitGTK(executable_path=webdriver_path)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/tests/.venv/lib/python3.11/site-packages/selenium/webdriver/webkitgtk/webdriver.py", line 66, in __init__
    super().__init__(
TypeError: WebDriver.__init__() got an unexpected keyword argument 'desired_capabilities'

As you can see inspecting selenium.webdriver.webkitgtk.webdriver.py, the constructor of RemoteWebDriver does not accept desired_capabilities

If I remove that param desired_capabilities=desired_capabilities I get:

python3.11 test_drivers.py 
Traceback (most recent call last):
  File "/tests/mytest.py", line 4, in <module>
    driver = WebKitGTK(executable_path=webdriver_path)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/tests/.venv/lib/python3.11/site-packages/selenium/webdriver/webkitgtk/webdriver.py", line 66, in __init__
    super().__init__(
  File "/tests/.venv/lib/python3.11/site-packages/selenium/webdriver/remote/webdriver.py", line 188, in __init__
    capabilities = options.to_capabilities()
                   ^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'to_capabilities'

So I have to replace desired_capabilities=desired_capabilities with options=options

And then it just runs ok!

Is it a bug or I'm missing something??

How can we reproduce the issue?

from selenium.webdriver import WebKitGTK

webdriver_path: str = "/usr/bin/WebKitWebDriver"
driver = WebKitGTK(executable_path=webdriver_path)
driver.get("https://google.com")

Relevant log output

python3.11 mytest.py 
Traceback (most recent call last):
  File "/tests/mytest.py", line 4, in <module>
    driver = WebKitGTK(executable_path=webdriver_path)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/tests/.venv/lib/python3.11/site-packages/selenium/webdriver/webkitgtk/webdriver.py", line 66, in __init__
    super().__init__(

These special webkit classes aren't really maintained as well as the other drivers; desired_capabilities should be deleted, and a default options class should be created by default.

I believe it can be done like in safari.webdriver, but I will ask before opening a pull request:
did I understand correctly that in this class we should stop accepting desired_capabilities as argument and create default options inside the class instance, as it was done in the commit ?
