🌟 Summary

Improved formatting consistency in GitHub Actions YAML files and dataset examples.

📊 Key Changes

• Standardized quotes usage in GitHub Actions YAML files (ci.yaml, format.yml, links.yml, stale.yml) from single to double quotes for string values.
• Removed unnecessary whitespace in YAML files to enhance readability and consistency.
• Updated dataset YAML files (coco8-pose.yaml, coco8-seg.yaml, coco8.yaml, dota8.yaml) to have consistent spacing around comments and key-value assignments.

🎯 Purpose & Impact

• These changes mainly improve the readability and style consistency of the codebase, leading to easier maintenance and better collaboration experience for developers.
• No direct impact on end-users is expected, as these are internal changes that don't alter the functionality of the code.
• Future developers will benefit from more predictable formatting and cleaner code when browsing the repository or contributing to it. 🛠️
