Note

Low Risk
Low risk text-only changes that adjust user-facing error strings in the Bright Data dataset tool and release CLI; no logic or behavior changes.

Overview
Fixes typos in BrightDataDatasetTool._run exception messages (occured → occurred).

Updates crewai_devtools release/tag workflow error handlers to report failures accurately (e.g., "Failed to create/push tag", "Failed to create GitHub Release", "Failed to trigger PyPI publish workflow", and clearer failures for git checkout main/git pull).
