Log Message:
py-black: update to 23.12.0.

## 23.12.0

### Highlights

It's almost 2024, which means it's time for a new edition of _Black_'s stable style!
Together with this release, we'll put out an alpha release 24.1a1 showcasing the \ 
draft
2024 stable style, which we'll finalize in the January release. Please try it out and
[share your feedback](https://github.com/psf/black/issues/4042).

This release (23.12.0) will still produce the 2023 style. Most but not all of the
changes in `--preview` mode will be in the 2024 stable style.

### Stable style

- Fix bug where `# fmt: off` automatically dedents when used with the `--line-ranges`
  option, even when it is not within the specified line range. (#4084)
- Fix feature detection for parenthesized context managers (#4104)

### Preview style

- Prefer more equal signs before a break when splitting chained assignments (#4010)
- Standalone form feed characters at the module level are no longer removed (#4021)
- Additional cases of immediately nested tuples, lists, and dictionaries are now
  indented less (#4012)
- Allow empty lines at the beginning of all blocks, except immediately before a
  docstring (#4060)
- Fix crash in preview mode when using a short `--line-length` (#4086)
- Keep suites consisting of only an ellipsis on their own lines if they are not
  functions or class definitions (#4066) (#4103)

### Configuration

- `--line-ranges` now skips _Black_'s internal stability check in `--safe` mode. This
  avoids a crash on rare inputs that have many unformatted same-content lines. \ 
(#4034)

### Packaging

- Upgrade to mypy 1.7.1 (#4049) (#4069)
- Faster compiled wheels are now available for CPython 3.12 (#4070)

### Integrations

- Enable 3.12 CI (#4035)
- Build docker images in parallel (#4054)
- Build docker images with 3.12 (#4055)
