docs: bug-bisect: rewrite to better match the other bisecting text

Rewrite the short document on bisecting kernel bugs. The new text
improves .config handling, brings a mention of 'git bisect skip', and
explains what to do after the bisection finished -- including trying a
revert to verify the result. The rewrite at the same time removes the
unrelated and outdated section on 'Devices not appearing' and replaces
some sentences about bug reporting with a pointer to the document
covering that topic in detail.

This overall brings the approach close to the one in the recently added
text Documentation/admin-guide/verify-bugs-and-bisect-regressions.rst.
As those two texts serve a similar purpose for different audiences,
mention that document in the head of this one and outline when the
other might be the better one to follow.
