Feature or enhancement

zipfile.Path is developed primarily as zipp
and synced downstream into the stdlib, per the development
methodology.
It was last synced from zipp 3.23 in gh-135276. This issue tracks the refresh
to zipp 4.1.2.

Three behavior changes are in scope:

• Path.iterdir() raises NotADirectoryError instead of ValueError when
  the path is not a directory (Raise NotADirectoryError from Path.iterdir jaraco/zipp#154, released in zipp 4.1.0). This is
  a breaking change — NotADirectoryError is an OSError, not a ValueError,
  so callers catching ValueError are affected. Main only; no backport.
• glob() and rglob() character classes follow shell semantics
  (Fix negated glob character classes jaraco/zipp#162, released in zipp 4.1.1): a leading ! negates, ^ is a
  literal, and neither matches a path separator. Previously the character set
  was passed through to the regex engine unchanged, so [!a] and [^a] were
  both treated as regex negation and could match separators.
• The workaround for the stacklevel bug in PyPy < 7.3.19 is removed
  (Stop working around bug in PyPy < 7.3.18 jaraco/zipp#149, released in zipp 4.0.0).

The remaining changes are test and lint cleanups that keep the two trees
byte-identical.

The str() fix also included in zipp 3.23.1 is being handled separately as a
backportable bugfix in gh-100609, and this refresh will build on it.
