Fix: ensure setup_logging does not modify the root logger

[My-laniaKeA]

Issue
Attempting to log after executing pipeline.run() may result in an error. This issue arises due to setup_logging(), which modifies the root logger using getLogger(), potentially causing unintended side effects.

Proposed fix
Modify setup_logging() to ensure it configures a dedicated logger for the pipeline.

@My-laniaKeA - should this not be "distilabel" to have the parent level and not a sibling?
