[3.12] gh-99203: shutil.make_archive(): restore select CPython <= 3.10.5 behavior (GH-99802) (#107998)

gh-99203: shutil.make_archive(): restore select CPython <= 3.10.5 behavior (GH-99802)

Restore following CPython <= 3.10.5 behavior of shutil.make_archive()
that went away as part of gh-93160:

Do not create an empty archive if root_dir is not a directory, and, in
that case, raise FileNotFoundError or NotADirectoryError regardless
of format choice. Beyond the brought-back behavior, the function may
now also raise these exceptions in dry_run mode.
(cherry picked from commit a86df298df5b02e2d69ea6879e9ed10a7adb85d0)
