Move 10up-toolkit to production dependencies; Update to latest version.

Description of the Change

This PR closes #138 by moving the 10up-toolkit from devDependencies to dependencies, making it available in the Node production environment.

I also cleaned up some files in the block theme that don't need to be there since the root config files should take precedence.

Lastly, I updated 10up-toolkit to the latest version across the entire project.

Closes #138
