[Pedantic] README.md encourages violation of the project's own copyright notice

[jake-arkinstall]

README.md instructs people that:

Add the apply_format and git-pre-commit-format scripts to your repositories.
You can either copy them (maybe in a scripts/ sub-directory) or add this whole repository as a git submodule.

But copying those scripts alone would technically be in violation of the project's own copyright permission notice:

The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software

Including the copyright notice inside both apply-format and git-pre-commit-format would resolve this.
