v1.6.0: Major improvements and changes

Changelog

• Fix the wrong e-mail used for the GitHub Actions bot when committing.
• Add repository code owners (currently, it's only me for now).
• The script will automatically exit if one_pr is disabled and squash_commits is enabled.
• Fix an error in update-repos.lua that would exit the script if no commit message was provided.
• Use single-quoting in commits and titles, which will allow other symbols such as !.
• Automatically adjust directory name. You can freely add / at the end or at the beginning and the script will attempt to adjust it.
• Improve Windows support. Previously, if you ran the scripts on Windows, it wouldn't work.
  • It is still recommended to use Ubuntu on GitHub Actions, though.
• Repository names can include .git at the end. Previously, this affected when getting the default branches and in other code utilities.
• Add a security policy to let the users know how to properly report errors.
• Add pull request labeling, allowing as many labels as you want.
• Use github.action_path when running the scripts, which speeds up the process by a few seconds, as the workflow previously cloned the scripts.
