Allow for .copier-answers.yml to recide in .config

[KalleDK]

Actual Situation

To help declutter the root directory and keep configs together

https://github.com/dot-config/dot-config.github.io

Desired Situation

I would like to keep one more file out of the root, and keep it collected in the .config folder

Proposed solution

It could be a priotized list

• .copier-answer.yml
• .config/.copier-answer.yml

This would then be backwards compatible and shouldn't break any templates

I know that it works to do following

copier update -a .\.config\.copier-answers.yml

But would be nice to work out of the box :)
