wrong link in Usage documentation

[clyra]

Hi,

The Usage section says that you should run:

cookiecutter gh:oncleben31/homeassistant-custom-component \ --checkout=2021.1.1

There's a missing "cookiecutter" there as there's no homeassistant-custom-component repo (from oncleben31):

The repository https://github.com/oncleben31/homeassistant-custom-component.git could not be found, have you made a typo?

So it really should be:

cookiecutter gh:oncleben31/cookiecutter-homeassistant-custom-component --checkout=2021.1.1

thx.
