Write a 'setup' script

[Noviny]

There's a bunch of stuff you will need to do anytime you clone this which we can automate.

Things that immediately spring to mind:

1. rename the scope to a name of your choice
2. (probably) set up the website with create-react-app | next | gatsby
3. Definitely more things

This will need to be interactive so someone can make choices.
I would probably but this as a package in manypkg so it doesn't gunk up the starter, but happy to start it here and migrate it out.

Interesting, and not a bad idea. A Github Action may be useful?
