Update Ultralytics Actions with OpenAI GPT-4 PR Summary

[pderrenger]

This pull request adds an improved Ultralytics Actions workflow to automatically format code and documentation to the new Ultralytics official standards maintained at https://github.com/ultralytics/actions.

Six individual actions are run by default now including a new PR Summary utilizing OpenAI GPT-4. Disable individual actions by setting them to false or removing their line, i.e. delete 'markdown: true' line to disable markdown formatting.

Note that additional spellings have been added to the Ultralytics spelling dictionary and frontmatter is now ignored by markdown formatters per your feedback.

To customize an action use a pyproject.toml file in this repo. For details see https://github.com/ultralytics/actions.
