Example Package: Automatically replace placeholders

[retlehs]

Create functionality, possibly within the Acorn CLI, to handle doing a search and replace on the placeholders in https://github.com/roots/acorn-example-package:

• vendor-name
• example-package
• VendorName
• ExamplePackage
• ExampleServiceProvider

I think we can add this to acorn-example-package and then have users run composer create-package roots/acorn-example-package ... and then have some prompts show up.

Bouncing this back to acorn-example-package, but if you disagree with this approach, feel free to yeet it back to me.
