[PATCH v2] Documentation: kunit: document --summary and --failed options

[Eugenio Zuccarelli <eugenio.zuccarelli@gmail.com>]

Commit 062a9dd9bad7 ("kunit: tool: Only print the summary") and commit
3c67a2c09b3c ("kunit: tool: print failed tests only") added the --summary
and --failed options to kunit.py, but the matching entries in the
run_wrapper documentation were never added.

Add descriptions for both options next to the other output options, so
the documentation lists the arguments the tool actually accepts.

An LLM-based coding assistant helped draft these entries; I checked them
against kunit.py and kunit_parser.py.

  trailer is no longer described in Documentation/process.

 - ``--junit``: If set, stores the test results in JUnit XML format and prints to `stdout` or
   saves to a file if a filename is specified.
 
+- ``--summary``: If set, prints only the summary line for parsed test
+  results, rather than the result of every individual test. Does nothing

+- ``--failed``: If set, prints only the tests that failed or crashed, along

 - ``--filter``: Specifies filters on test attributes, for example, ``speed!=slow``.
   Multiple filters can be used by wrapping input in quotes and separating filters
   by commas. Example: ``--filter "speed>slow, module=example"``.
