'dist' getting bundled with every release

[jaraco]

In this comment I was demonstrating a mapping of "top-level" Python packages to their distributions and discovered to my surprise that skeleton-based projects, probably at the introduction of 0df4081 have started including dist in their packages. It seems the find_namespace is really generous, so finds any directory, including dist. Let's exclude that.

I've released new versions of those packages indicated in the other comment with the referenced commit and they no longer expose 'dist' as top-level:

~ $ pip-run -q jaraco.functools jaraco.classes pyyaml -- -c "import importlib.metadata as md, collections; dists = md.distributions(); pk
g_to_dist = collections.defaultdict(list); [pkg_to_dist[pkg].append(dist.metadata['Name']) for dist in dists for pkg in dist.read_text('t
op_level.txt').split()]; import pprint; pprint.pprint(dict(pkg_to_dist))"
