fix: disable usage of root logger (#7296)

* fix: disable usage of root logger `logging.basicConfig` configures Python's root logger. This prohibits fine control of logging, overwrites logging configuration done outside the package, and is not best practice. Instead, the used logger is now configured directly, and the root logger is untouched. Example: If yolov5 is used as part of another project with some sophisticated logging, the internal `logging.basicConfig` call overwrites all the external configuration. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Update general.py * Update general.py * Comment kaggle * Uncomment kaggle Co-authored-by: Maximilian Strobel <Maximilian.Strobel@infineon.com> Co-authored-by: Glenn Jocher <glenn.jocher@ultralytics.com> Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com>
