The commits, in order:

1. This removes pyproject.toml, as this project is not a Python project that would require installation. (The pyproject.toml file also would not work, as it attempts a dynamic version configuration where no dynamic version configuration source is present.) It also removes the duplicated configuration from pyproject.toml.
2. This changes the user attribution for the automated commits to Ultralytics Actions instead of @glenn-jocher. (git's user.name is not a GitHub username; it should be a realname.) This is good Git hygiene, not to mention that since this will evidently be used in Ultralytics's open-source projects that welcome external contributions, it sounds amiss that @glenn-jocher would be personally auto-formatting PRs.
3. The action.yml file in this repository did not strictly adhere to the GitHub action schema; the type for inputs.default is string. (Your editor should highlight this as you edit the file; mine did.)
4. Finally, there was a simple typo; while Tom Preston-Werner is indeed the author of the TOML file format, the extension isn't his first name. 😁

🌟 Summary

This PR updates defaults and enhances spelling checks in Ultralytics' GitHub Actions.

📊 Key Changes

• Changed the defaults of Python, docstrings, markdown, and spelling inputs from Boolean false to String 'false'.
• Updated the installation comment about the necessity of tomli for codespell.
• Enhanced the codespell command to include a specified ignore-words list and files/directories to skip during the spell check.
• Modified the git config to use a more generic Ultralytics Actions user for commits made by GitHub Actions.

🎯 Purpose & Impact

• Ensuring input defaults are consistent and properly formatted as strings provides clarity and prevents potential confusion or errors in workflows.
• Documentation improvements aid maintainers in understanding dependencies' purposes.
• The customized codespell parameters reduce false positives by ignoring certain terms and skipping specified files, leading to more accurate spelling checks.
• Changing the commit authorship to a generic user account makes automated actions distinct and unified across Ultralytics repositories, offering better traceability and consistency.

These changes enhance the automation of repository maintenance tasks, potentially improving code quality and reducing the manual workload on developers. 🚀
