chore(action.yml): update action name, description, author, and repository information

style(action.yml): update branding color and add additional keywords
style(action.yml): update GitHub Token description and specify node version to use

The action name, description, author, and repository information have been updated to better reflect the purpose and ownership of the GitWiz action. The branding color has been changed to purple, and additional keywords related to the action have been added for better discoverability. The GitHub Token description has been capitalized for consistency, and the node version to use has been updated to node18 for compatibility.
