Motivation

This PR addresses the good first issue to modernize string formatting across the Optuna codebase, specifically replacing older syntax with cleaner f-strings as requested in #6305.

Description of the changes

  • Updated tutorial/10_key_features/005_visualization.py to use an f-string instead of .format().

Fixes #6305
