Configure Dependabot Label to Empty

[threeal]

This issue proposes configuring the Dependabot label in the dependabot.yaml file as an empty array. This approach is suggested to prevent Dependabot from setting labels on the pull requests it creates, as the specified labels may not exist in other projects, particularly in new projects forked from this project. The suggestion is primarily made for the same reason mentioned in threeal/project-starter#43.
