python3-importlib-metadata: upgrade 4.4.0 -> 4.5.0

Upstream release notes:

v4.5.0
Issue 319: Remove SelectableGroups deprecation exception for flake8.

Previous upgrade release notes:

v4.4.0
Issue 300: Restore compatibility in the result from Distribution.entry_points
(EntryPoints) to honor expectations in older implementations and issuing
deprecation warnings for these cases: EntryPoints objects are once again
mutable, allowing for sort() and other list-based mutation operations. Avoid
deprecation warnings by casting to a mutable sequence (e.g.
list(dist.entry_points).sort()). EntryPoints results once again allow for
access by index. To avoid deprecation warnings, cast the result to a Sequence
first (e.g. tuple(dist.entry_points)[0]).

v4.3.1
Issue 320: Fix issue where normalized name for eggs was incorrectly solicited,
leading to metadata being unavailable for eggs.
