Supporting YAML configuration with cookiecutter

[kpinc]

Hi,

I'd like to have cookiecutter support for YAML configuration files. This would use plaster-yaml.

Would you accept a patch that asks whether to use YAML, JSON, or PasteDeploy .ini config files?
This would have to be based on the "main" branch. Besides main being the development branch, it is the only branch which packages with a pyproject.toml file.

Alternately, I can fork the pyramid-cookiecutter-starter.

See also, the pyramid_cookbook PR #233, a tutorial on using YAML config files.

FYI. There's a branch here that patches the cookiecutter to support yaml config files.

I've not submitted a PR because it depends on other project's acceptance of other PRs. (See: plaster PR #37) If it makes sense to submit the PR now I'll go ahead and do that.
