Provide an easier way to change copyright format

[kaspar-p]

Currently the only way to change the copyright from

Copyright of X, 2018 - 2022

to

Copyrighted by X, 2018 - 2022

is to:

• Run copyright delete -r ./
• Change the configuration file to support the new copyright
• Run copyright update -r ./

There should be a better way to handle this, but nothing easy comes to mind. Perhaps some sort of web interface like a text editor where they can change the copyrights and they will automatically be run on some pre-selected Github repositories.
