fix: remove constant variable causing always-false condition in bench_isolation_forest

[sonarqube-agent]

Removed the constant variable assignment with_decision_function_histograms = False that was causing an always-constant condition in an if statement. This eliminates dead code and resolves the SonarQube critical issue where the variable was never used as intended.

python:S5797 - Replace this expression; used as a condition it will always be constant. • CRITICAL • View issue

Location: benchmarks/bench_isolation_forest.py:135

Why is this an issue?

When a constant is used as a condition, either it has no effect on the execution flow and it can be removed, or some code will never be executed and it is a bug.

What changed

Removes the constant variable assignment with_decision_function_histograms = False which was the root cause of the code smell. This variable was always False and was later used as a condition in an if statement, meaning the condition would always be constant. By removing this assignment, the source of the constant expression used as a condition is eliminated, and the associated dead code is no longer reachable.
