[PATCH] Documentation/maintainer-tip: Update Link tag rules

[Borislav Petkov <bp@kernel.org>]

From: "Borislav Petkov (AMD)" <bp@alien8.de>

Remove the rule about Link tag pointing to the upstream submission of
a patch as this is "frowned upon" now. Clarify when a Link tag should be
used.

    A convenient way to associate ``Link:`` trailers with the commit
    message is to use markdown-like bracketed notation, for example::

      A similar approach was attempted before as part of a different
      effort [1], but the initial implementation caused too many
      regressions [2], so it was backed out and reimplemented.

-   You can also use ``Link:`` trailers to indicate the origin of the
-   patch when applying it to your git tree. In that case, please use the
-   dedicated ``patch.msgid.link`` domain instead of ``lore.kernel.org``.

 Please do not use combined tags, e.g. ``Reported-and-tested-by``, as
 they just complicate automated extraction of tags.
