Make pathlib ABCs usable by zipfile.Path

Feature or enhancement

This issue covers the final tasks needed to make the pathlib ABCs worthy of using in zipfile.Path (i.e. zipp.Path).

Tasks

• Rename PurePathBase to JoinablePath, and split PathBase into ReadablePath and WritablePath
  • https://github.com/python/cpython/pull/128523
• Make WritablePath a sibling (not subclass) of ReadablePath
  • https://github.com/python/cpython/pull/129014
• Add ReadablePath.info
  • https://github.com/python/cpython/pull/127730
• Subclass abc.ABC from JoinablePath, and make parser abstract
  • https://github.com/python/cpython/pull/128745
• Make type-checking more consistent
  • https://github.com/python/cpython/pull/130199
• Move metadata reading into ReadablePath.info; remove ReadablePath._copy_reader
  • https://github.com/python/cpython/pull/129897
• Move metadata writing into WritablePath._write_info(); remove WritablePath._copy_writer
  • https://github.com/python/cpython/pull/130238
• Merge pathlib._abc into pathlib.types
  • https://github.com/python/cpython/pull/130747
  • https://github.com/python/cpython/pull/130748

  • https://github.com/python/cpython/pull/131018
• Tests: add tests for WritablePath
  • https://github.com/python/cpython/pull/131112
• Tests: parametrize copy() tests
  • https://github.com/python/cpython/pull/131168
• Finalise copy() implementation
  • https://github.com/python/cpython/pull/131259
• Add type annotations?
• Sync code to pathlib-abc PyPI package
  • https://github.com/python/cpython/pull/131315
• Update pathlib-abc documentation
• Publish new version of pathlib-abc
• Merge PR to jaraco/zipp
  • https://github.com/jaraco/zipp/pull/132

Start by reviewing the remaining unchecked tasks in the issue, especially type annotations and the pathlib-abc integration with jaraco/zipp PR #132. Read the linked pathlib ABC and zipfile.Path work before deciding whether anything remains to implement; done means the outstanding task is completed and the related tests and package synchronization remain consistent.
