[UltralyticsAssistant]

This pull request significantly enhances the Ultralytics Actions workflow, introducing support for JSON and CSS formatting, alongside intelligent issue and PR handling. This includes automatic labeling, spam detection, abuse identification, and off-topic filtering, all powered by OpenAI GPT-4o. These updates ensure a more efficient and organized workflow, adhering to the latest Ultralytics standards.

Key Enhancements:

• Expanded Formatting Support: Ultralytics Actions now automatically formats JSON, CSS, Python, Markdown, and Swift files to maintain consistent code quality across projects.
• Smart PR and Issue Handling: The workflow now includes intelligent auto-labeling for issues and pull requests, spam detection, and filtering of abusive or off-topic content, ensuring a cleaner and more focused repository environment.
• Enhanced PR Summaries: PR summaries are now generated using GPT-4o, providing concise and informative overviews of changes to streamline the review process.

Actions Overview:

• Six Default Actions: The workflow now runs six actions by default, including Python code formatting with Ruff, Markdown styling with Prettier, docstring formatting with docformatter, Swift code formatting with swift-format, spell-checking with codespell, and broken link detection with Lychee.
• Customization: You can easily customize or disable individual actions by modifying the corresponding lines in the workflow file (e.g., remove the 'markdown: true' line to disable Markdown formatting).
• Customization with pyproject.toml: Additional customizations can be applied using a pyproject.toml file, allowing you to tailor the action to your project’s specific needs.

Additional Updates:

• Ultralytics Spelling Dictionary: New spellings have been added to the Ultralytics spelling dictionary to enhance accuracy.
