fix: accept all alternative extentions for copier.yaml

[12rambau]

Fix #50

I try to detect any "copier" file with a yaml-like extension. My guess is that there should be only one so if multiple exist I take the first one.

@GenevieveBuckley do you think it's enough to solve the issue you raised?

This does fix the problem, thank you!

I think it would be nice to add a try/except statement around the copier_yaml line, so that we can raise a sensible error to the user, eg: "No copier.yaml configuration file found"

This is the error message that happens right now if no copier.yaml/copier.yml file is found. I think a new user would struggle to figure out what the cause of the problem was.

        # set the template dir and the associated copier.yaml file
        template_dir = template_dir or self.default_template_dir
        files = template_dir.glob("copier.*")
>       copier_yaml = next(f for f in files if f.suffix in [".yaml", ".yml"])
E       StopIteration
