chore(deps): bump the python-packages group with 3 updates

[dependabot]

Bumps the python-packages group with 3 updates: black, pytest and platformdirs.

Updates black from 25.11.0 to 25.12.0

Release notes

Sourced from black's releases.

25.12.0

Please test out the draft 2026 style in version 26.1a1! This style will be finalized in the January release (26.1.0). Most of the changes in --preview will be in the 2026 stable style, but not all. Please share your feedback!

This release (25.12.0) will still produce the 2025 style.

Highlights

• Black no longer supports running with Python 3.9 (#4842)

Stable style

• Fix bug where comments preceding # fmt: off/# fmt: on blocks were incorrectly removed, particularly affecting Jupytext's # %% [markdown] comments (#4845)
• Fix crash when multiple # fmt: skip comments are used in a multi-part if-clause, on string literals, or on dictionary entries with long lines (#4872)
• Fix possible crash when fmt: directives aren't on the top level (#4856)

Preview style

• Fix fmt: skip skipping the line after instead of the line it's on (#4855)
• Remove unnecessary parentheses from the left-hand side of assignments while preserving magic trailing commas and intentional multiline formatting (#4865)
• Fix fix_fmt_skip_in_one_liners crashing on with statements (#4853)
• Fix fix_fmt_skip_in_one_liners crashing on annotated parameters (#4854)
• Fix new lines being added after imports with # fmt: skip on them (#4894)

Packaging

• Releases now include arm64 Windows binaries and wheels (#4814)

Updates pytest from 9.0.1 to 9.0.2

Release notes

Sourced from pytest's releases.

9.0.2

pytest 9.0.2 (2025-12-06)

Bug fixes

• #13896: The terminal progress feature added in pytest 9.0.0 has been disabled by default, except on Windows, due to compatibility issues with some terminal emulators.

  You may enable it again by passing -p terminalprogress. We may enable it by default again once compatibility improves in the future.

  Additionally, when the environment variable TERM is dumb, the escape codes are no longer emitted, even if the plugin is enabled.

• #13904: Fixed the TOML type of the tmp_path_retention_count settings in the API reference from number to string.

• #13946: The private config.inicfg attribute was changed in a breaking manner in pytest 9.0.0. Due to its usage in the ecosystem, it is now restored to working order using a compatibility shim. It will be deprecated in pytest 9.1 and removed in pytest 10.

• #13965: Fixed quadratic-time behavior when handling unittest subtests in Python 3.10.

Improved documentation

• #4492: The API Reference now contains cross-reference-able documentation of pytest's command-line flags <command-line-flags>.
