[PATCH] docs: submitting-patches: suggest adding previous version links

[SeongJae Park <sj@kernel.org>]

For review of patches that revisioned multiple times, patch changelogs
are very useful.  Adding actual links to the previous versions can
further help the review.  Using such links, reviewers can double check
the changelog by themselves, and find previous discussions.  Nowadays
having such links (e.g., lore.kernel.org archive links) is easy and
reliable.  Suggest adding such links if available.
