[🐛 Bug]: logging to /dev/null remains dangling

[alexey-pelykh]

What happened?

ResourceWarning: unclosed file <_io.BufferedWriter name='/dev/null'>

that's caused by a bug in the following lines of code:

selenium/py/selenium/webdriver/common/service.py

Lines 138 to 142 in c64ed7d

	if self.log_output != PIPE:
	if isinstance(self.log_output, TextIO):
	self.log_output.close()
	elif isinstance(self.log_output, int):
	os.close(self.log_output)

possibly this case is not covered:

selenium/py/selenium/webdriver/common/service.py

Lines 61 to 62 in c64ed7d

	elif log_output is None or log_output is subprocess.DEVNULL:
	self.log_output = open(os.devnull, "wb")

likely was introduced in #12637

How can we reproduce the issue?

Launch the Chrome WebDriver via Selenium
