Subject: [PATCH 2/6] docs/kunit/start: Skip wrapper run command

From: SeongJae Park <sjpark@...zon.de>

The kunit 'Getting Started' document first shows the wrapper running
command.  However, a new user who simply following the command might
encounter a failure like below:

    $ ./tools/testing/kunit/kunit.py run
    Traceback (most recent call last):
      File "./tools/testing/kunit/kunit.py", line 140, in <module>
        main(sys.argv[1:])
      File "./tools/testing/kunit/kunit.py", line 126, in main
        linux = kunit_kernel.LinuxSourceTree()
      File "/home/sjpark/linux/tools/testing/kunit/kunit_kernel.py", line 85, in __init__
        self._kconfig.read_from_file(KUNITCONFIG_PATH)
      File "/home/sjpark/linux/tools/testing/kunit/kunit_config.py", line 65, in read_from_file
        with open(path, 'r') as f:
    FileNotFoundError: [Errno 2] No such file or directory: 'kunitconfig'

Though the reason of the failure ('kunitconfig') is explained in its
next section, it would be better to reduce any failure that user might
encounter.  This commit removes the example command for the reason.
