[igt-dev] [PATCH i-g-t 10/18] scripts/igt_doc.py: sets the minimal version to run the script

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

according with vermin, the minimal version for this script is 3.6 due
to:

	  'argparse' module requires 2.7, 3.2
	  'enumerate' member requires 2.3, 3.0
	  'json' module requires 2.6, 3.0
	  'open(encoding)' requires !2, 3.0
	  'os.path.realpath' member requires 2.2, 3.0
	  'sorted' member requires 2.4, 3.0
	  'sorted(key)' requires 2.4, 3.0
	  'str.format' member requires 2.6, 3.0
	  'subprocess' module requires 2.4, 3.0
	  'subprocess.run' member requires !2, 3.5
	  'sys.version_info' member requires 2.0, 3.0
	  `with` requires 2.5, 3.0
	  f-strings require !2, 3.6
	  print(expr) requires 2.0, 3.0

So, print an error if one tries to run with an older version.
