Reference Issues/PRs

Closes #30352

What does this implement/fix? Explain your changes.

  • Introduces a new boolean parameter plot_f1_baseline (default: False) to
    :meth:~sklearn.metrics.PrecisionRecallDisplay.plot, which draws the
    hyperbolic F₁-score baseline (Flach & Kull 2015) for the “always-positive”
    classifier.
  • For that baseline curve, style kwargs are forwarded via the existing
    f1_baseline_kw argument.
  • The .plot docstring (with .. versionadded:: 1.8) was updated so that
    this parameter appears in the HTML API reference.
  • A minimal smoke-test was added in
    sklearn/metrics/_plot/tests/test_precision_recall_display.py to verify
    that custom style kwargs (e.g. linestyle) are actually applied.

Any other comments?

All existing tests pass and the new smoke-test covers the styling branch.
